unable to launch WindowsXp image on openstack - openstack

I tried openstack on my laptop, my setup is like this
Host Machine: Windows 7
Virtualisation: VirtualBox
Ubuntu12 is running on this VirtualBox, On this Ubuntu12, I installed OpenStack Essex packages with qemu as hypervisor, and added few uec linux images on to glance, I was able to access linux images using ssh and vnc, it was great success.
Now, It has become very challenging to upload Windows image , it was really a night mare I tried all possible ways, searched in google found lot of solutions, but nothing worked, at last I converted WindowsXp.vdi file to WindowsXp.img using VBoxManage and added to glance, once I launch it I am getting blue screen error and windowsxp is horribly
restarting......................... So please help to resolve this issue

Your windows images (server or desktop) will BSOD without the correct drivers for the virtualization that you have chosen. Try installing the windows image with one of the drivers at http://www.claunia.com/qemu/drivers/index.html (QEMU drivers) and see how it goes.
Please note: Windows is notoriously difficult to run on any cloud not just OpenStack. In addition to the drivers, you will wrestle with image format (like you have) and initialization problems (otherwise all the images come up with that same GUIDs).

How to get Centos Stream 9 / RHEL 9 to run as a VM on Apple Mac M1/M2 Chipset

So you've bought a shinny new mac M1/M2 and you realise that you can't get virtualisation to work.
I tried every hypervisor and tried a lot of combinations
So it took me days to get the following working with visualisation since VirtualBox 7.0.2 which stated it would work for M1/M2 chipset.
What I wanted to achieve was the following:
Shared Folders
Bridged Network Interface
RHEL based OS
Sounds simple right!! Well this was a lot of trial and error. I read a lot of articles with people patching software just to get the basics going and I couldn't find the patched files so wanted an out-of-the-box solution.
So after hours of trying Centos Stream 8 which all our servers are on and what our development environments are on, I tried installing Ubuntu 20.04 in parallels with shared folders but without bridged networking and this was the light bulb moment when I realised it was the pagesize of the OS, so RHEL 8 will not work.
So I tried RHEL 9 in parallels and it booted up and installed. I then tried to install the Guest Tools so I can get Shared Folders to work but this then highlighted a bug in the Guest Tool which really disappointed me considering they state they have a working hypervisor which can work with aarch64 but this wasn't the case, however it does work on Ubuntu just not RHEL 9.
I then tried VMWare Fusion which failed miserably, you can launch the VM but no Shared Folders or no Bridged Network. Quickly move on to something I tried earlier which was UTM.
Now UTM has 3 modes and it is important to know the 3 (correct me if i'm wrong).
Virtualisation with QEMU
Virtualisation with Apple Hypervisor
Emulation (everything is run via Rosetta)
I tried QEMU but there was issues with Shared Folders so wasted no time in not spending anymore time using QEMU.
I then decided to try the Apple Hypervisor and I noticed everything was running faster than it did in QEMU. Mounting the Shared Folder was easy and simple, and you can mount it in you /etc/fstab for permanently mount, you also can set the Bridged Network in the settings.
So after a lot of trial and error I was able to get a RHEL based OS VM running with UTM using Apple Hypervisor with the same functionality as I used to have with vagrant.

Openstack, a small image for a tiny flavor

Recently I installed openstack using devstack on my laptop. The problem I'm facing is to launch an instance, since my pc have poor ressources (32 bits, 4 Go Ram, 20Go free space), I need to deploy a very small image.
I tried an iso image for an ubuntu, I downloaded also a image from Ubuntu Cloud images but both of them can't be started. All I want to do is to launch an instance, install java, Tomcat server.
Any advice about an image that I can use?
Try Ubuntu Server Cloud Image
It will run perfectly with 512 MB of RAM.
Also stop unwanted services to save memory. Like stop ssh, sendmail, crond If you are not using them.
Use ubuntu cloud images. Make sure your cloud image is also 32bit.
While spawning instance, see that you look into Nova Security groups to allow ports which you might use.
devstack has cirros built-in. It is probably as small as you can get. It is a limited distro, but you should be able to download the jdk installer and run it.
You may need to download a 32 bit cirros image. The cirros distro downloads are available here:
https://launchpad.net/cirros/+milestone/0.3.0
This image should work for you:
https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-i386-disk.img
You can try any image which are at **https://docs.openstack.org/image-guide/obtain-images.html.
In these Ubuntu image is one which you can use and install applications on it.
It comes with default username ubuntu and you can set new password using cloud-init of heat template or manually while launching the instance.

Glassfish admin console slow loading

Today I stopped/started my GlassfishV3 instance and now I cannot access the addmin console located at http://servername:4848/. The screen says: "The admin console is loading..." This is going on forever now.
I have tried as follows:
I have tried adding the following entry to my domain.xml located at /glassfishv3/glassfish/domains/domain1/config as suggested in another Stack Overflow Q&A but after restarting the server still no luck.
<java-options>-Dcom.sun.enterprise.tools.admingui.NO_NETWORK=true</java-options>
I have also installed glassfishv3 on my local machine and cannot recreate the problem.I can go to http://localhost:4848 without any problem.
I have also looked at the server.log and jvm.log files located under the /glassfishv3/glassfish/domains/domain1/logs and nothing there that shed some light.
Any help would be very much appreciated
I had similar symptoms, and I tried some of what Dario had suggested as well, but it didn't work. It could be that I had a unique configuration for my dev env: I'm running Glassfish 3.1 on a VirtualBox Ubuntu 11.04 64-bit guest on a Windows 7 64-bit host. Quite by accident, I discovered an additional symptom: if I turned off the network on the Ubuntu guest, the console would load successfully on a localhost browser instance. That is, on the Ubuntu guest with the network off, I could successfully navigate to http://localhost:4848 and show the Glassfish admin console as expected. However, if the Ubuntu guest's network was on, I had the exact behavior suggested by the original poster: http://localhost:4848 would just sit forever on the inial loading page.
To make a long story short, I found that adding the following argument to the JVM options for server-config fixed the problem:
-Djava.net.preferIPv4Stack=true
When I made that change and restarted the Glassfish server, everything worked.
(Note that I also had in place some of the other settings recommended above, i.e., NO_NETWORK=true, and I'd adjusted the JVM memory footprint and set it to -server instead of -client. It could be that these settings are required as well, though they weren't sufficient on their own in my case.)
I was having this exact same problem. I could deploy in run mode, but it would hang forever in Debug mode. IntelliJ was hanging on the breakpoints. I muted the breakpoints, and glassfish3 worked good as new. I didn't have to change any domain.xml settings. Check your breakpoints!
I found a solution to my problem. Setting the java-option to NO_NETWORK to true did not work so I upgraded from 3.0.1 to 3.1 and it got fixed. Not immediately though, I had to stop/start the Glassfish server a couple of times before I got into the admin console without any really long delays.
Solution
The solution was to upgrade from the command line using the pkg utility.
You can find the steps in this link:
http://download.oracle.com/docs/cd/E18930_01/html/821-2437/gkthu.html#gktjf
Or do as follows:
Go to as-install-parent/bin
./pkg image-update
as-install-parent/glassfish/bin/asadmin start-domain --upgrade domain-name
as-install-parent/glassfish/bin/asadmin start-domain domain-name
UPDATE
I had peformance issues again and I found this other solution in Joshi's tech blog:
http://joshitech.blogspot.com/2009/09/glassfish-application-server.html
Basically add the following jvm options in the domain.xml. It should increase Glassfish boot up and deployment performance:
<jvm-options>-server</jvm-options>
<jvm-options>-Xms3000m</jvm-options>
<jvm-options>-Xmx3000m</jvm-options>
<jvm-options>-XX:MaxPermSize=192m</jvm-options>
<jvm-options>-XX:NewRatio=2</jvm-options>
<jvm-options>-XX:+AggressiveHeap</jvm-options>
<jvm-options>-XX:+AggressiveOpts</jvm-options>
<jvm-options>-XX:+UseParallelGC</jvm-options>
<jvm-options>-XX:+UseParallelOldGC</jvm-options>
<jvm-options>-XX:ParallelGCThreads=5</jvm-options>
I don't know if you are referencing this answer, but there is a second step described (disabling update module).
Two more ideas:
Check if the NO_NETWORK=true option really works (there should be no ads in GF admin console)
Watch the server.log (glassfish-install-dir/glassfis/domains/domain1/logs) during startup and look for the last log entry before the delay occurs. This could be a hint for the source of the delay.
Beware of blindly following Dario's example unless you've lots more RAM than most do.
-Xms3000m gives 3gb to Glassfish. Do YOU have that much spare RAM?
I tried this on my 4gb Mac with 1gb for Glassfish. Made no discernable difference at all...performance still sux.

CSS cross browser compatibility on Ubuntu

I'm currently working in web development and my default desktop is Ubuntu and I'm kind of happy with the setup and applications I got going. But I need to test web pages for cross browser compatibility while still being on Ubuntu.
I have gone through hell trying to get IE7 or IE8 (with wine) to run on ubuntu and when they finally worked they were very buggy and the graphics/scrolling was insanely slow.
Of course there is the option of virtual box but again, too much GBytes just to run a small application!
So to all the CSS gurus out there, how can I continue with my beloved Ubuntu and still deliver a good quality (tested) page.
Thank you.
Edit:
Update for freshness:
I now use the paid service from browserstack.com to provide the multitude of different browser testing environments via flash tunnelling. I'm a paid user, but there is an initial free trial period. browserstack has freed me of the need to run the windows os on my machines in any form, virtual image or otherwise. Since it also allows tunnelling, I can host the site on my local machine but still test in browserstack browsers. I consider the monthly fee money very well spent.
End Edit
Various options I have tried, including "the final solution": free downloadable windows testing OSes from microsoft
I've tried a number of the options below, but virtualbox may be your best bet for full & complete testing, especially because in a professional capacity you often have to test ie8, ie7 -and- ie6. Which gets tricky with only a single os installed. So in order of simplest and most shallowly testing to most complex and most fully testing:
browserlab.adobe.com
A newer, interesting online solution is: browserlab.adobe.com. It's actually very specific and fast compared to browsershots. It only gives you screenshots, but it's a great first step. So I do recommend that for purely visual (and thus relatively shallow) testing.
Browsershots.org
And while browsershots.org is also something that you should use for an overview experience of what users might see, you really can't get by without the real browsers for javascript and behavior testing (instead of just display & rendering testing that browsershots provides). The delay before you can see the images is also killer.
Dual booting into windows
Another that I've tried is dual booting, I work 99% of my time in ubuntu, and I have windows installed & available to dual boot into. Not a fast way to test, but if you don't have any other way to access ie, it should work for at least the latest version.
Remote desktop-ing over to a running windows box
Before I mention the "covers-all-the-bases" option, another useful possibility is to set up a windows machine and boot it up and connect to it via remote desktop so that you can work from one machine and test from both.
The final solution, using virtualbox
Finally, the mother of all solutions, using virtualbox:
Luckily (I know you said you didn't like the virtualbox solution, and I know it's an annoying setup process, but...) Microsoft provides available-for-a-year-or-more virtualmachine distros with different versions of ie pre-installed, available without the need for a license for a year or so before you'd have to update the virtualmachine, #

Installing a virtualmachine from microsoft's freely available browser testing images
Because this guide to setup on ubuntu is no longer available in full anywhere else, just in case you or someone else actually need it I feel compelled to include the actual details of the install process that were suggested to me on the ubuntu forums and worked when I went through them. I apologize for their length. Courtesy of the now anonymous original poster on the ubuntu forums:

HOWTO: run IE6, IE7, IE8 on Linux in
VirtualBox You need: virtualbox, qemu,
wine
Code: apt-get install virtualbox qemu
wine
Download the free(!) Microsoft
Internet Explorer Application
Compatibility Check VPC Images here:
http://www.microsoft.com/downloads/details.aspx?FamilyId=21EABB90-958F-4B64-B5F1-73D0A413C8EF&displaylang=en
(Note: you don't have to download the
full pack, you can cherry pick
specific combinations of XP/Vista and
IE6-8)
Extract the VPC image(s) with wine
(double-click). (Note: it might take a
while before the first window shows
up)
Turn the VPC image(s) into (a) VMWare
image(s) (which is/are readable by
VirtualBox): qemu-img convert -f vpc
image.vhd -O vmdk image.vmdk
Setup a new VM in VirtualBox, using
the vmdk image as an existing disk.
Boot it, you will see the Windows boot
progress bar and ... it will BSOD
shortly after.
Fixing the BSOD:
The BSOD is caused because the virtual
Windows tries to load processor
drivers for the wrong processor (it is
not running on VirtualPC proc, but on
VirtualBox proc). Or something like
that... We need to force Windows not
to attempt to load drivers for the
processor (it doesn't need any proc
drivers, because it's all virtual
anyway). Start safe mode by
(frantically) hitting F8 at Windows
boot and choosing safe mode.
Ignore all the 'New hardware' detected
warnings (we will deal with those
later). Start a command box and run
the following command to disable the
loading of processor drivers:
Code: sc config processor start=
disabled (note the space between '='
and 'disabled'!)
Restart the virtual Windows, it should
now boot all the way to the Windows
Desktop.
Now just when you think you can start
browsing the web with IE, you will
find out that the virtual Windows
needs to install the drivers for the
AMD PCnet NIC, which are located on
the Windows install disk. Fortunately
for those without a Windows install
disk, there is another way :)
Download AMD PCnet drivers here:
http://www.amd.com/us-en/ConnectivitySolutions/ProductInformation/0,,50_2330_6629_2452%5E2454%5E2486,00.html
Make an iso file containing the
drivers. I used Brasero for
simplicity. Choose to create a Data
Project, add the zip file (or the
unzipped files, saves you a step in
Windows), create the iso. No need to
burn an actual cd!
Stop the virtual Windows, edit the
settings in VirtualBox: mount your
brand new iso.
Start the virtual Windows, when it
asks to install the drivers for the
PCnet nick, point it to the (unzipped)
drivers. Et voila! You have teh
innernets! (Now you can also try to
install the other drivers it complains
for, but it's not really necessary)
The image README says the image will expire after about a year. In my experience the system gets hobbled against multi-hour use, but is still usable for the kind of short periods that you might want when booting up to test a website. At worst you might have to go through these steps again, so be sure to put them somewhere where you can find them again after a year or so.
I think setting up a virtual machine (Virtualbox or VMWare or...) with a proper Windows will be your only (local) option.
I you don't have one, buy a used Windows XP license. XP is cheap (around 20-30 euros here in Germany, for example) and all relevant versions of IE run on it. Home edition is enough. No need for Windows 7 or anything.
You could install IETester on that to get all the IE versions on one OS. IETester has flaws and is not always 100% reliable in what it renders, but for a general CSS compatibility check it should be okay.
I've never tried IE using Wine, but even trying to imagine the combination gives me goose bumps :D
If you have a copy of Windows you could install it in a virtual machine (Virtualbox is a good, free option). Or if you don't mind a lot of lag time and publicly exposing your web pages you could use a service like BrowserShots.
I have not tried this on Ubuntu or anything but windows - but this seems to be a pretty good testing system over the web.
http://spoon.net/browsers/
however, I think your best result would be to use a VM if possible.
I have to add my voice to those opting for VirtualBox.
VMs are the only way to get an accurate representation of how IE platforms behave. They also allow you to keep your main Linux install free of WINE and IE gunk, which is otherwise always troublesome and fragile. (Especially if you're trying to run multiple IEs, which is unreliable and inaccurate even under Windows).
They're not necessarily that big, if you take care to prune the unneeded features, turn off swap, compact the disc image and so on. My XPSP3 test image is just over 800MB.
I didn't want to install all this stuff as I wanted to move forward quick.
I found public AWS images with pre installed browser that you just can start and use.
http://www.hens-teeth.net/html/products/cross_browser_testing.php
If you already have an AWS account this will take you only 5 min. Make sure that you enable the RDP port on the incoming traffic in your security group.
As I use ubuntu I was looking for a way to connect from it to MS Win.
I'm connection on to them via remote desktop.
The way to go here is rdesktop, a command line utility for Windows Remote Desktop. (sudo apt-get install rdesktop)
If you feel like a GUI use tsclient. It's very close to the windows version.
From a work flow perspective I develop for Chrome in Ubuntu first, then have a look at the other browsers via browserlab.adobe.com.
After that I start my new AWS instance to debug.
The small AWS Windows instance is a $0.12 per hour (http://aws.amazon.com/ec2/#pricing). I can work for a long time on that before it's worth installing all this stuff.
CrossBrowserTesting.com works from Linux. Allows you to access Mac, Windows, and Ubuntu configurations and all the browsers loaded on them via vinagre vnc client.

Running Visual Studio in Parallels for mac - problem with debugging sites sitting in os x drive

I've installed parallels desktop on my MacBook to be able to run Visual Studio 2008 in a XP installation. Everything works great except when I decided to put my websites in my sites folder in the os x file system (Which by default automatically happens because the My Documents folder is mapped to the Mac's Documents folder, and I'd rather put my code there so that both OS's can easily access it.).
When trying to build or debug I get this error:
Failed to start monitoring changes to 'Z:\xxx...'
How do I get it so that I can get it to work under Parallels, from the shared drive?
Parallels uses network drives to simulate folders on OS X, and Windows can't monitor changes to network drives, so if you do this directly, it'll be broken.
If you want to keep them in sync though, use Live Mesh (http://www.mesh.com) and install it on both the host and guest. A little roundabout, but it'll make it so both copies are maintained (and Live Mesh is handy for other things too)
I recently flipped over to putting my source code onto my Mac volume, so I could use Time Machine to back it up and immediately got this same problem with my ASP.NET app. Other, procedural applications, built just fine, by the way.
I tried all sorts of things, including using Samba on the Mac side to share the directory, which led into the "too many BIOS commands" error described elsewhere. Unfortunately for me, the Registry hacks to fix that problem never worked for some reason.
I finally found another solution that avoids Samba and just uses the regular Parallels Shared Folders. It too is a Registry hack, but this one simply turns off file change monitoring for ASP.NET. It is a bit heavy-handed, but gets my builds to work again.
The reference for this change is here:
http://support.microsoft.com/kb/911272
The downside to this approach, I am finding, is that you need to be more deliberate about recompiling, or restarting the web server, as changes during development don't just magically appear anymore. I am still deciding whether that is a useful tradeoff.
UPDATE: After several days of this, development was just too difficult and, sadly, what I reverted to was keeping my source inside the Parallels virtual disk. To enable Time Machine backups and Spotlight searches, I used a lightweight MS utility called SyncToy to push stuff out of Parallels and out to my Mac drive several times a day. Despite the high hack factor, it is working well.
I know this isnt strictly a solution but VMware fusion is superior when it comes to shared drive space on a virtual machine. Its what i currently use and hasn't let me down thus far...
People always give me odd looks when they see visual studio on my mac :P
Try moving the project on to the VMs C drive. Its not an ideal situation, but you can access the VMs C drive from OS X.
I have a similar problem with a php site that uses an MS Access database (its a clients system). I have alias's that point to the php site on the VM so that I can still do all of my coding in OS X. To do this I created a network share on the VM and then connected to it from OS X. Once connected make the alias's. If the network drive is not open and you open a file in OS X it will try to reconnect. It means the VM will need to be running to get to the files, but this isn't normally a problem since the VM is hosting the site anyways.
.NET has funny issues trying to debug the objects on a network drive.
make sure that you have full trust on your local network between your Mac and XP install.
Check out: http://msdn.microsoft.com/en-us/library/aa302361.aspx
If at the end of that research, I"m afraid you will have to look into the option of keeping it on the VMDisk and moving it when you need it.
I see a similar problem on my machine connected to the windows domain. My documents is mapped to a network share and I can't debug|run|etc. I had to eventually move to my local disk for debugging.
I definately recommend Live Mesh as a way to keep directories in sync. Just keep the VM's directory in sync with the Mac's directory.
Or use SVN to hold copies in both machines and do commit/update as appropriate. That way you get versioning, history and if your project grows bigger, you can share with other devs.
I know dropbox also has history and sharing, but not check in/check out/conflicts and all the other advantages of a real source control.
Oh, if you have money you can also go for TFS. I would but it is just too expensive :)
