Xen HVM: Can I make virtualisations if I'm a guest (domU)?


Maybe strange question. But as far as I understand HVM is full emulation of hardware. I have a VDS with 16gb ram and 8xeon, it's domU of XEN HVM. I don't want to run tons of daemons in one plate..

So my question is can I install any virtualisation host inside? KVM, XEN, OPENVIZ? If no maybe any other solutions exists?

my domU is freebsd (KVM port exists)

Solution

So my question is can I install any virtualisation host inside?

Xen(only Linux), VirtualBox(any supported OS) and OpenVZ.

Xen/OpenVZ performance overhead typically 0.1%-4%.

  • +0 – To run KVM, you need a processor that supports hardware virtualization. domU it has't. Try VirtualBox. — Jan 29, 2011 at 14:09
