Subject: [PATCH] selinux: Avoid label reservations for type
= none during restart
To: libvir-list@xxxxxxxxxx
The problem is libvirt kills the guests during libvirt restart if more than
guest has security type as none. This is because, libvirt as part of guest-
reconnect tries to reserve the security labels. In case of type=none, the range
of security context happen to be same for several guests. During reservation,
the second attempt to reserve the same range fails and the Guests would be
killed. The fix is to avoid reserving labels for type = none during libvirt
restart.
