[libvirt] [PATCH] Ensure non-root can read /proc/meminfo file in LXC containers
From: "Daniel P. Berrange" <berrange(a)redhat.com>
By default files in a FUSE mount can only be accessed by the
user which created them, even if the file permissions would
otherwise allow it. To allow other users to access the FUSE
mount the 'allow_other' mount option must be used. This bug
prevented non-root users in an LXC container from reading
the /proc/meminfo file.
