Public bug reported:

Binary package hint: qemu-kvm

Installed qemu-kvm, but it was *very* slow (while using virt-manager).
Looked in /var/log/libvirt/qemu/xxxx.log and noticed that user libvirt-
qemu had no access to /dev/kvm (access denied error) and that it was
unable to use the KVM full virtualization support. Placing user libvirt-
qemu in the kvm group did not solve the issue.

Looked at /dev/kvm an noticed it was own by root.

Changed group ownership to kvm and, in combination with libvirt-qemu
being in the kvm-group, this dramatically increased the performance!

ls -al /dev/ | grep kvm
crw-rw----  1 root kvm      10, 232 2011-01-15 22:06 kvm
