[Pkg-libvirt-maintainers] Bug#695744: "libvirtError: An error occurred, but the cause is unknown" on virDomainDestroy()

[noxdafox]

Package: python-libvirt
Version: 1.0.0-1
Severity: normal
Tags: upstream

I'm running several Virtual Machines on a single system with qemu-kvm; their
lifecycle is short and the system is under pretty heavy load.

Occasionally, when shutting down an environment I get the following error:

File "/usr/lib/python2.7/dist-packages/libvirt.py", line 734, in destroy
    if ret == -1: raise libvirtError ('virDomainDestroy() failed', dom=self)
libvirtError: An error occurred, but the cause is unknown

Looking at the QEMU log everything seems fine to me:

I'm running libvirt 1.0.0 at the moment but the problem seems to occur also
with the 0.9.13 release.
