[sheepdog] sheepdog + libvirt problems

[Vasiliy Tolstov]

Hi again. I'm stress test libvirt with sheepdog storage backend, and
have errors while try to start 20-30 domains in the same time.
As i see libvirt refresh pool each time when in creates volume, so
dog node info -r run each time, in case of 20-30 vm in the same time
libvirt says about:
internal error: pool 'sheepdog' has asynchronous jobs running.
so - may be add timestamp to output to determine on which time info is valid ?
or how to speedup pool refresh?
