Comment 31 for bug 1057024

So I did a fresh quantal install and then (after installing kvm and virtual machine manager and then adding user to the libvirtd group) . The issue was present and when i checked getfacl /dev/kvm it had group:---

Then after the reboot i checked getfacl again it had group:rw-
When i tried booting the vm using the Virtual Machine manager it worked!

So apparently a reboot solved the issue.
