I was installing vagrant with virtualbox provision. When I am running it on Amazon EC2, then it doesn't work saying:
* Running VirtualBox in a Xen environment is not supported
EC2 uses xen virtualization. On the other hand, its working fine on Windows Azure Virtual Machines which uses a customized version of Hyper-V.
So,cant we use virtualbox in Xen but in Hyper-V?
Are you sure that HyperV allow you to start the VM, I don't think this is possible using current hardware VT technology without slow painful emulation instead of virtualization.

Can I install Hyper-V in Linux? Suppose our Hyper-V Manager install in windows server . Do I able to backup on Linux? What will be the best solution to backup Hyper-V Manager?
I am afraid, you have not described the problem clearly or defined your problem. Hyper-V Manager is Microsoft's virtualization management platform and does not support installation on Linux systems, but it can back up with Linux virtual machines(e.g. CentOS RHEL etc.).

You can not install Hyper-v on Linux.
To reduce costs you can use Hyper-v server without passing to Windows server and enable the hyper-v feature.
Veeam backup is the most powerful solution to make backups for Hyper-v or vCenter.
I have a problem with Docker running the nanoserver.
My environment: I Installed docker on a Win10 (developer build from microsoft) Virtual Machine (cause host is still Win7 with no default Docker support because of Hyper-V). I installed docker on the virgin image so no 3rd-party programs can cause the error. I also have already checked if Hyper-V is enabled.
But I think this Screenshot says everything:
Also Googled the problem, but everything i found wasn't in a Docker context.
FYI: I want to use the Docker container for running a network rendering slave which should only see one cpu core (for licensing reasons), maybe someone has another option for this.
so you are trying to run Docker on Windows 10 which is a VM on Windows 7? I suppose this is not possible. You are trying to run a virtualization platform inside a virtualized Host (your Windows 10 machine). This nested virtualization is not supported by Windows 7 afaik.
Nested virtualization is supported on Windows 10 Build 10565 and later (this must be your virtualization host).
Have you tried to create and run a Hyper-V VM inside that Windows 10 VM? this will also fail.
Which Intel virtualizaton techniques are necessary for Docker?
On a Linux system running on a Intel cpu, what Virtualization Technologies by Intel are necessary to fullfill the execution of a Docker container? E.g. there are VT-X, ...
Or is there no need of using such a technology because Docker is somehow different to existing virtualization solutions like VirtualBox. In this case, why is there no need?
None. Docker uses a completely different system - it's not running a virtual machine so much as a super chroot. See the question below:
Can I run Docker directly on a non VT-X machine (no Virtual Machine used)?
The tutorials that tell you you'll need VT-x are usually based on running docker in Windows (on Hyper-V) or in VirtualBox.
I have converted a CentOS 7.2 Hyper-V VHDX instance to a VirtualBox 5.1.10 VDI instance using the VBoxManage clone command and am using this VirtualBox instance on a Mac. Everything works well except the guest instance will not run in full screen mode. I have tried to install Guest Applications but it fails each time.
Is there anything that I am missing in this process?
I need to configure a virtual Windows 7 x64 for running games. I used the pre-installed KVM on CentOs 7 to install the virtual machine but unfortunately the video controller was not recognized as Nvidia GPU and no drivers could be installed.
The virtual Windows is running fine by itself. I searched the web for a way to configure the virtual video controller with no success. In one article, however, someone mentioned that KVM does not support 3D. Is that correct? If so, what other virtualization software can I use to make a fully functional Windows?
