As reported on https://bugs.debian.org/892431, without this rule, when launching a QEMU KVM instance, an error occurs immediately upon launching the QEMU process such as: Could not open backing file: Could not open '/var/lib/nova/instances/_base/affe96668a4c64ef380ff1c71b4caec17039080e': Permission denied The other instance disk images are already covered by the existing rule: /**/disk{,.*} r Signed-off-by: intrigeri <intrigeri@boum.org>
