Re: [libvirt] libvirtd crash upon virsh destroy

Running libvirt v1.0.0, with

I cannot reproduce reliably), is that libvirtd crashes sometimes on
a destroy (sequence of events and crash log below).
I was wondering if anyone had any insights as to the cause of this
crash, or even if any commits after v1.0.0 might address this. If I
can provide anymore information to help debug this I would be happy
to try and provide it. At the time of this crash, the instance being
destroyed did not have any RBD attachments, it was just running off
its local LVM.
Sequence of events:
1.) virsh destroy ID
End of file while reading data: Input/output error ; error: Failed
to reconnect to the hypervisor
(libvirtd at this point has crashed)
if you are able to reproduce this reasonably easily, it would be nice
if you could capture a stack trace with GDB. eg "thread apply all bt"
from a GDB prompt when it has crashed
/me ought to see if we can get the automatic libvirt crash log to
include a stack trace, since the log messages are pretty useless
on their own.
