OpenStack Compute (nova)

HVM mode on Xen Hypervisor via libvirt

Asked by Li Wang

hi, all

We use Xen as the Hypervisor via libvirt on Nova, and want to run some virtual machines in HVM mode.

I've searched around, and not found any usefull infomations about it.

I digged into the code, finding that Nova configures libvirt to use "linux" (PV) mode while the Hypervisor is Xen, with the cheetah template in 2012.1(Essex), and programmed (nova/virt/libvirt/connection.py:line 1445) in 2012.2(Folsom).

Is there a mature solution for this, or is there a plan to support both PV and HVM mode through libvirt with Xen Hypervisor?

thanks.

maybe you could turn this into a bug and get someone to look it into it.

If you're thinking of Windows support you might be better off using the xenapi driver and XenServer/XCP.
