The approach of subscribing on first stat API call and then waiting for receiving of performance event from sdk to process the call originates in times when every vz libvirt connections spawns its own sdk connection. Thus without this waiting virsh stat call would return empty stats. Now with single sdk connection this scheme is unnecessary complicated. This patch subscribes to performance events on first domain appearence and unsubscribe on its removing.

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.
