Is it possible to transfer a VirtualBox VM from one server to another without shutting it down? Is there any way to achive this? Does this technology have a name to identify it?
As far as I know Xen provides such a functionality, but when I played around with it, I had major issues in stability. For instance shutting down my Xen server using the reset-button, did not only simply restart, but had to be configured and checked first.
Same for KVM, providing a very good way to configure the "ideal" computer. I was impressed by it's vastness, but in terms of performance I encountered big issues. Does KVM provide this functionality?
I tried myself with VMWare as well. It is very similar to VirtualBox, but I couldn't find any possibility for the above question.
