Public bug reported:
I have my setup for libvirt/qemu such that ISO images do not get owned
by libvirt:kvm when assigned to a domain. This means I have to run with
/etc/libvirt/qemu.conf with:
user=root
group=root
dynamic_ownership=0
This has been working since at least Natty. With the latest updates to
libvirt/qemu on Precise, this setup does not work anymore: starting an
existing domain will fail with access denied on the ISO, or on the disk
image:
I tried, together with Jean-Baptiste, a series of combinations on these
3 parameters. The *only* ones that work are the default setup:
# user=root
#group=root
#dynamic_ownership=1
Of course, this causes all used ISOs and images to be owned by
libvirt:kvm (interestingly, a snapshot image will be owned by
root:root); this breaks daily ISO updates.
