[libvirt] [PATCH] LXC: Fix return code evaulation in lxcCheckNetNsSupport()

by Richard Weinberger

Commit b9dd878f (util: make it easier to grab only regular command exit) changed the call semantics of virCommandRun() and therefore of virRun() too. But lxcCheckNetNsSupport() was not updated. As consequence of this lxcCheckNetNsSupport always failed and broke LXC.

[libvirt] [PATCH] Use a static initializer for static mutexes

by Daniel P. Berrange

Now that we ditched our custom pthread impl for Win32, we can use PTHREAD_MUTEX_INITIALIZER for static mutexes.
