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 lsb_release -a No LSB modules are available.
