[libvirt] [PATCH] Set security label on FD for virDomainOpenGraphics

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The virDomainOpenGraphics method accepts a UNIX socket FD from
the client app. It must set the label on this FD otherwise QEMU
will be prevented from receiving it with recvmsg.
