You should set the cpu_mode=none, if you want to use 'qemu' libvirt type.

Hi,

I am trying to install Ice-house on ubuntu 12.04 and unable to start
nova-compute service as it throws

Please see below configuration for nova-compute.

nova-compute.conf

[DEFAULT]
compute_driver=libvirt.LibvirtDriver
[libvirt]
virt_type=qemu

Does anyone has any idea? Pointers in the right direction are highly
appreciated.

Regards,
Rajshree
