Re: [libvirt] PATCH: 24/25: Update python error reporting



The virGetLastError() method is now stored in a thread local
and virConnGetLastError() is deprecated, so switch to only
use the former. Also, no need to copy the error object since
it is thread local already thus guarenteed not to change behind
our backs
