Subject: [PATCH] qemu_domain: Modify access to a NVMe disk iff needed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If a domain has a NVMe disk it already has the access configured.
Trying to configure it again on a commit or some other operation
is wrong and condemned to failure.
