Need help on 3 aspects of Cloudstack. It has become the major point of our decision to go ahead with the implementation
Serial port debugging:
We do lot of serial port kernel debugging in Windows and UNIX. There is no out of box support for it . We need to go to VMWARE level to enable it , and we want to shield users from this. Any suggestions on this front.
Memory Snapshoting
People here are used for VMWare memory snapshoting feature. Also the ease with which Workstation/vSphere manages the Snapshots. Is there any way we can use that in Cloudstack? Our implementation is on VMWare , so we already have things in place , so just want to know , how to get it integrated with Cloudstack.
VMWare Tools
Whenever we create an instance from ISO's , we see that Mouse do not work. It is really painful to install the VMWare tools and get the mouse working. Is there any solution for this problem.
Need immediate feedback on Apache CloudStack?
Send your question to the mailing list
Need specific features to be added?
Talk to support Vendor such as Citrix.
Serial port debugging: -- What Steps you follow in enabling it in vmware
Memory Snapshoting: -- Cloudstack provides the snapshot feature ,but after taking snapshot you can not create vm from that snapshot,first you will have to convert that snapshot in templates and then you can create vm
VMWare Tools -- You can use attach iso facility of cloudstack .Initially install operating system with tabs but after installation attach vmware-tools.iso to that vm from cloudstack and install it on browser itself.

We have one existing vmware virtualization contains 4 host, each host contains nearly 6vms, Now we are planning to deploy Open stack, The thing which Open stack version is good to deploy in VM, i have installed Centos 7 on VM.
I have to confirm which version of open stack is good for real time environment.
If anyone knows pls suggest version, and installation URl it will much better understanding to me,
Get started with devstack which is easier to install as you just have to run one script(stack.sh) and it will deploy all the clients on same machine. You can use that to practice creating VMs, making security groups and assigning floating ip to the vms. After that try to configure on a multinode architecture and I would suggest that you get a Ravello account (https://www.ravellosystems.com/) for that instead of using your own servers. This link might help you in configuration (https://docs.oracle.com/cd/E36784_01/html/E54155/archover.html#scrolltoc).
Search "openstack multinode deployment" on google. You will have plenty of links.
I am beginning to study the use of virtual machines with realtime applications, specifically network applications.
While I do understand the limitations and concerns, I'd like to get ideas as to how to get started on this task.
I am going to use a DPDK sample application over Linux, and probably use VMWare for starters. However, I do not know what my first steps with respect to setting up VMWare should be.
First I think it is better to use open source solution like QUEM/KVM for your virtualization platform. Many platform exist for run high performance network functions on virtualized platforms you can see OpenNetVM for example in order to get basic ideas.
I have the IBM Business Process Manager Advanced 7.5 installed.
Question:
Is it possible to install and run newer version - IBM BPM 8.5 on the same machine?
I worry about ports conflict (for example port 9043 to IBM Console).
Maybe I should ask how to change default port configuration?
Please help.
Technically it can be possible, however I suggest you do not do this as ibm bpm requires a lot of system resources to run and installing two versions of ibm bpm can make the system slower than ever before.
However I have seen multiple instances of same ibm bpm version running on a single cluster on server VM. This is practically stable and in use from considerable tenure.
PS. - I had administered a huge ibm bpm infra containing 80+ ibm bpm servers.
As Gas already commented, in theory this is possible. But you have to be aware, that IBM BPM is not only using the specified ports for web access, it also uses ports for internal communication. In my opinion, this is not an easy task to get right.
On the other hand, the system requirements for IBM BPM are quite challenging for the server, if You want to run both instances in parallel, you should consider that your server will need to be capable. WebSphere is kind of greedy and not really designed to share its resources ;)
Yes, you can run multiple versions of BPM on the same system. The primary concerns are going to be port conflict and OS system resources. Use the BPMConfig to create a new profile and installation that is on different ports. On my lab machines with VMs, I install all the BPM installs with the default ports and only have one (1) running at a time. If I need 2, I just spin up a new VM from the base template and go from there.
By Default, the port conflicts are addressed by the WebSphere Application server code. If needed you can specify "initialPortAssignment" for Dmgr, node and cluster members while creating the environment using BPMConfig command. You can even specify specific port numbers using the
https://www.ibm.com/support/knowledgecenter/en/SSFPJS_8.6.0/com.ibm.wbpm.ref.doc/topics/samplecfgprops.html
You can also provide Websphere options like "-startingPort starting_port | -portsFile ports_file_path | -defaultPorts" for Dmgr bpm.dmgr.profileOptions= and nodes bpm.de.node.#.profileOptions in the BPMConfig properties file. For cluster members just have option to indicate the starting port.
REf: https://www.ibm.com/support/knowledgecenter/cs/SSAW57_8.5.5/com.ibm.websphere.nd.multiplatform.doc/ae/rxml_manageprofiles.html
I would not advise on changing the port numbers once you start using the BPM environment.
As indicated by others make sure you have enough resources if you are planning to run both environments at the same time.
Yes, I am using two versions for evaluation. Port conflicts can be handled using server (WebSphere Integrated Solutions Console) console or BPMConfig utils.
On Windows, I've used NEWT in the past, but it's difficult to use, not current (but I can find old copies on non-MS sites), and difficult though possible to degrade just the app's view of the network without messing up everything else on the machine like the VPN connection and NAS volumes.
On Mac, the Network Link Conditioner that is available with Xcode is far too limited and in particular doesn't model bursts, which is my current immediate interest.
I'm also interested in Windows programs running in a VMware VM, and that's already going through an emulated network connector. I wonder if that can be made to do the traffic shaping?
In summary, can someone suggest a tool that I ought to be using for this?
I guess http://henrydu.com/blog/how-to/simulate-a-slow-link-by-linux-bridge-123.html should work on your mac. It uses traffic control with ifconfig, something you might want to google for.
With OpenStack's architecture, is it possible to, for instance, have a PowerPC64 (Altivec) machine, a Intel CoreDuo machine, and a ARMv6 all on the same cluster?
Or is this impossible, because of the restrictions in building buildpacks when deploying to multiple architectures?
EDIT: Whoops, I meant OpenStack, not OpenShift ;)
The answer above is correct (answer from developercorey).
Although whether this suits you depends on how its managed and what your trying to achieve. Typically when you add servers with different physical attributes such as CPU, Disk, Network cards etc you group them into different host aggregates.
By default when you launch a VM it will try and find a suitable host, but you can also tag it, so for example if your VM required alot of disk IO, you might want to place it on a host that has SSD drivers. So you can put those hosts into a 'SSD' aggregate, and then when launching your VM you can make sure it goes to a host in that aggregate.
If your just trying to make the most out of the hardware you have, then I don't see any issue by mixing them.
I don't think that they have to be, but I do believe that they only build packages for 1 or 2 architechtures, so I'm not sure how many options you really have there.
