I accidentally disabled my virtualbox host-only network in Network and sharing folder and it disappeared, and now I cannot do anything in Genymotion due to a network error. How do I find the network to enable it or get Genymotion to work again?
Genymobile soft is supposed to recreate the apropriate network on the fly when needed.
Make sure you use the last version and it should be fine.

I noticed that there is a way to control the ubuntu installed in virtual box using X11 in Window. My eclipse was running quite unsmoothly in virtual box. Therefore, I want to use X11 to help me programming better. But I don't know how to achieve that.
If you forward X11 and run Eclipse in VirtualBox you will almost certainly experience worse issues. X11 forwarding means that everything that was running in VirtualBox is still running in VirtualBox except now it's sent through a network connection to the host you're on. If you want to try it use this with ssh
ssh -X username#domain.com
then open the tool from the prompt and see if it helps. You may need to enable X11 from the sshd_config in /etc/ssh/sshd_config on the VirtualBox.
I was using SonicWall Global VPN for a long time and it was working perfectly. But I am having trouble in connecting it for last few days. I have tried the following, but nothing helped.
Uninstalled Hamachi VPN
Uninstalled and re-installed SonicWall
Turned-off firewall.
Turned off anti-viruses
But it is working fine in my friend's machine, it is working fine.
Not sure what is the problem with my machine.
Can anyone suggest any ideas ?
Sometimes sonic VPN is not working because ISAKMP packet sent option is not enable. We need to mark it restrict first packets.
steps:
1. Go to File menu
2. Select properties
3. Click to Restrict the size of the first ISAKMP packet sent.
What error are you getting while connecting ? If it's stuck in connecting , it would be the OS version and GVC versions are not compatible !
Windows 7 : GVC version 4.7
Windows 8 and above : 4.9.9
Is there any way to install OpenStack without using virtual box in a single machine?
You can install all openstack services(controller, compute, network) in a single node. But it's not recommended.
If you don't want to install virtualbox you can try VMware
You may also try LXC or XEN if you are using linux. Then create 3 virtual machines and install openstack 3 node configuration.
Yes, of course. Just make sure you have enough resources on the system (single machine) to bare OpenStack. You may use packstack do the All-in-One
deployment. Check out RDO.
There is a possibility of installing openstack(both 2 and 3 node architectures) in a single system. But, things are to be considered. Like the performance of the system used, the primary memory associated with it, the secondary memory that is available, e.t.c
If you're talking about development environment, sure! You don't need a VM at all, and can just install it on your laptop directly! Note that this is not a desirable configuration :)
Other ways are to use a different virtualization tool than VirtualBox, like KVM, or VMware stuff.
Virtual machine is nothing but a system with shared resources. Whatever we do on a VM can be replicated to an individual system.
Make sure you have VT enabled on the hardware , else you may have issues in creating instance on the Compute node.

Whatever you can install in single virtual machine , can also be installed on your machine directly.
After all your machine is much more powerful and stable than your virtual machine.
We use virtual machine just to leave our system intact in case something goes wrong. Just compare the time it would take you to delete and create another virtual machine with time and effort for formatting your entire laptop.
Also, we sometimes use virtual machine if we need to make a network of 2-3 computers for some functionality and we have got only one hardware.
I created with kvm virtual machünes on Ubuntu 14.04
If you create the virtual machines and the virtual networks you can use it.
For the easiest way if you use an orchestration/deployment tool e.g. Mirantis Fuel
Surprising no body talked about Dockers. You can run openstack in a docker container.
According to my experience, always try to install openstack on a fresh system( either on a freshly created VM or on a newly installed OS). I have installed openstack many times, and trust me no error will come just follow this link on a newly setup machine. For old system, I was stuck for 3 days, and only GOD knows where from the hell those errors were showing up.
PS: I have always tried ubuntu system.
Recently i just finished installing dummynet ipfw in Windows 8.1. I need to deactivate digital siganture requirements before able to install it. But after install it, desktop shows Test Mode 9600 on corner right down of desktop. After i removed it then i couldn't connect to internet until i uninstall dummynet from my network adapter. I wanted to work in dummynet ipfw but it seems impossible. Is there any solution for this?
Thanks
Check default ipfw rule. On FreeBSD initial ipfw ruleset typically defaults to ipfw add 65536 deny all from any to any and that's probably what stops your traffic.
You'll need to add a rule that would allow your traffic to get in and out to get your traffic going and, possibly, directed towards dummynet pipes, etc.
When I try to start debugging my windows phone 8 app in Emulator WVGA 512MB the following error message is showing
The Windows Phone Emulator wasn't able to connect to the Windows Phone operating system:
The emulator couldn't determine the host IP address, which is used to communicate with the guest virtual machine.
Some functionality may be disabled.
and the emulator is always showing The Windows Phone OS is starting...
Can't understand what's the problem. Please advice.
This worked for me (found here):
follow the following steps to solve this problem
1.go to network and sharing center
2.go to change adapter setting
3.go to v Ethernet (internal Ethernet port windows phone emulator internal switch)
4.right click it and enable it(if already enabled then disable and enable it again).
At last the problem is solved.
Open Hyper V Manager
Delete all installed Virtual Machines
Delete all Virtual Switches
Restart system
Rerun visual studio
Thanks to Shiv Kumar Ganesh
I had the same problem. After a long investigation and checking the event log, learned that windows firewall is blocking the emulator connecting to the virtual machine. With that information it is simple to fix the problem.
Yes! Just navigate to Control Panel -> System and Security -> Windows Firewall -> Allow app or feature through Windows Firewall. And click on Add another app button and browse the emulator's path (typically "C:\Program Files (x86)\Microsoft XDE\8.0\XDE.exe" but may vary based on your installation location). Choose the appropriate network type that you want and add the new item.
Now go back to VS and run your application (close any emulator instance that you have opened already), everything should work fine now!
the solution that worked for me :
open Hyper V
Select ur VM and go to Virtual Switch Manager.
Select Windows Phone Emulator Internal
if your connection is Internal then , check the Enable VLAN Identification option
press F5 from VS .
good luck!
Just reboot
No magic needed. Just reboot your development machine after installing Windows Phone SDK.
what your describing is usually due to a Firewall of a third party Anti-virus.
If your using Symantec follow this procedure https://stackoverflow.com/a/26326528/4446346
If your using Windows Firewall follow this procedure https://stackoverflow.com/a/27685167/4446346
and If you'r using AVG do the following procedure:
open AVG and go to-->Options-->Firewall Settings-->Expert mode-->Advanced Settings.
Check the "Allow any traffic from/to virtual machines supported by firewall"
and click "OK".
One more thing you must do is go to the "Windows Phone Emulator Internal Switch" and uncheck "AVG network filter driver"
open Network and Sharing Center-->Change Adapter Settings-->Properties
Uncheck "AVG network filter driver"
If you are loading the emulator for the first time, it behaves just like the phone (on first boot) where it will install the initial set of apps and configure them. Which is why the first start will take a long time. You can actually open Hyper-V manager and connect to the VM you had selected at the time of initiating debug - to see the actual progress of what is happening.
Hope this helps.
You can disable Hyper-V from Program and Features and reboot your machine twice. Everything will be default. Enable Hyper-V and reboot twice and everything should be working again.
Also you can check if your vEthernet (Internal Ethernet Port Windows Phone Emulator Internal Switch) in Network and Sharing Center is enabled (mine was not, and I got same error like you).
Check that you have enough free space in your hard drive.
If you have a computer with a touch-screen and get this error, it can be because Hyper-V is trying to port over the touchscreen-fx to the virtual device.
This is (when found) easily corrected:
Shut down all attempt at launching virtual devices.
Go to: Hyper-V Manager->Hyper-V-settings->Physical GPU:s // Uncheck box "use this GPU with RemoteFX"
Try uninstalling vmware player 12 if you have ,I have tried several ways but nothing works until I remove it.
Hope it could help you.
