When doing snapshots, the filesystem freeze function used the agent entering function that expects the qemud_driver unlocked. This might cause a deadlock of the qemu driver if the agent does not respond. The only call path of this function has the qemud_driver locked, so this patch changes the entering functions to those expecting the driver locked.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
