Hello,
I just updated from jaunty to karmic and then to lucid.
After that, I had the same problem and I could not boot my images any more.
Maybe apparmor was installed automatically and caused the problem when starting
a guest:
error: Failed to start domain 220_trxerdpd330_installtest
error: internal error unable to start guest: libvir: QEMU error : cannot change
to '114' group: Operation not permitted
after adding the following lines in /etc/apparmor.d/libvirt-qemu the problem
was solved:
capability setgid,
capability setuid,
The xml of my guest looks like this
domain type='kvm'
name220_trxerdpd330_installtest/name
uuid87cb0f4f-1d8f-4e8b-2a1f-4cda94aca1ec/uuid

When I mount a readonly cd image, I get similar errors:
I think there are two issues:
1. libvirt should not chown/chgrp/chmod images, especially not readonly images
2. apparmor profile should correspond to libvirt.
