Package: libvirt-daemon
Version: 1.2.8-1
Severity: normal
Dear Maintainer,
After booting my laptop (vedrfolnir) I am able to start a domain (xanadu) using
the GUI client (virt-manager). Logging in to the domain as root and using the
'shutdown -h now' command, the domain halts (apparently normally). That the
domain is halted is confirmed by ssh no longer working, no response using the
ping command, and virt-manager showing the domain as stopped.
Subsequent attempts to start the domain fail. The virt-manager GUI reports the
following stack-trace:
Error starting domain: error from service: CreateMachine: File exists
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper

if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: error from service: CreateMachine: File exists
Attempts to start the machine using virsh fail in a similar manner.
virsh # connect qemu:///system
virsh # start xanadu
error: Failed to start domain xanadu
error: error from service: CreateMachine: File exists
virsh #
Restarting the laptop (vedrfolnir) allows the domain (xanadu) to start but
after being shutdown, once again the domain cannot be started.
The log file for the virtual machine (/var/log/libvirt/qemu/xanadu.log) shows
the domain starting up but almost immediately (11 ms) failing, unfortunately
without logging any error.

2014-09-14 15:38:50.405+0000: shutting down
To me, this looks like a problem where starting a domain consumes or allocates
some resource that is not freed when that domain shuts down. I'm not sure
if this is libvirt's responsibility or qemu/kvm.
In case it helps, here is the domain's XML configuration:

I upgraded to the version of libvirt from experimental, but the problem
persisted.
I'm not sure what else I can do to help figure out what is going wrong, but
please let me know
if some other piece of information would be helpful.
Cheers,
Paul.
