![]() Though docker and lxc/lxd I don't think cares much if it is run inside a vm to matter much. I am not familiar enough on qemu to know how that handles and what it needs. Note, the virtualization extensions are not always required (depending on the vm software), but is helpful. The biggest factor doing is, that on the host VM image, you need to be sure the virtualization extensions are also exposed (often the vm, is only sees a simulated cpu, not the actual one). As neddy mentioned, it is not generally recommended on running a VM inside a VM, but is possible (though some VM software can have issues with doing this). If you are wanting a GUI, you are dealing more on the graphics. Having X is separate from a vm, in that the virtualization extensions have no effect on running X11. Maybe paravirtualisation is the only other possibility to try as I imagine full virtualization without hardware virtualization extensions may be rather slow. Well vps is X less, and I d like to have a vm with X inside it, which I can remotely access.

I am also curious to see, how a vm in a vm would perform, as I read with vmx or svm it could be rather good. I opened a ticket and asked my hoster, if it would be possible to get vmx or svm support on that vps. So I could try to do migration of a running vm from libvirt of my local box up to libvirt on host on the vps.įirst I thought, it would not be possible at all, then read about nested vm, then read that kvm will need hardware virtualization (vmx or svm) support, and then finally found out, that vps is configured without those two flags needed to do kvm virtualization. I thought, as the virtual server is quite powerfull (it compiles much faster, than my old baremetal gentoo box with its core2duo processors), I thought it is worth a try to run kvm host on the vps. Yes, the reason is just for testing purposes. Those that have never had a hard drive fail. Working and working fast enough to be useful is two different things. Their is nothing special about virtualisation and Virtualbox, so I would expect other hypervisors to work too. It operated but performance was terrible. One day I tried Virtualbox inside Virtualbox. It was better than runnig the laptop itself. I also used to boot the image in Virtualbox on Gentoo. ![]() I used Virtualbox on my work laptop, which I used to image from time to time as a backup. You want to run a Virtual Machine inside another virtual machine? Last edited by Elleni on Tue 8:40 am edited 1 time in total So is this possible ? And if not - are there any reasonable alternatives ?
