It is because when virtio is in use, OpenVZ's "fairsched" is disabled 
(which causes trouble for virtio network cards).

2.6.32 does not support OpenVZ, and therefore, kvm binary wants to use 
"fairsched", but doesn't find it and fails.

The solution is to add a dummy virtio card along the other network card 
(e1000) etc. Then, kvm would not use "fairsched" and everything would 
start properly.

Unless there are other workarounds I'm not aware of.
