Description Cole Robinson 2014-12-04 14:40:23 UTC

FWIW this is my first time trying libvirt + ceph integration.

$ rpm -q libvirt-daemon ceph
libvirt-daemon-1.2.9.1-2.fc21.x86_64
ceph-0.80.7-1.fc21.x86_64

$ cat test.xml
<pool type='rbd'>
  <name>f20-ceph</name>
  <source>
    <host name='192.168.124.101'/>
    <name>rbd</name>
  </source>
</pool>

$ sudo virsh pool-define test.xml
$ sudo virsh pool-start f20-ceph
<libvirt crashes>

Comment 1 Darryl Bond 2014-12-19 05:02:57 UTC

I suspect it is a bit wider than libvirt, segfaults with any ceph rbd command:
# rbd --cluster backup ls
rbdtest
rbdtest1
zztest

Comment 2 Boris Ranto 2014-12-22 08:12:17 UTC

This appears to be a duplicate of bz1144794. It should be fixed in latest ceph release (version 1:0.80.7-2.fc21.x86_64) available in the testing repo. Could you please retest with the updated packages?

Comment 3 Darryl Bond 2014-12-22 21:05:55 UTC

Ceph 1:0.80.7-2.fc21 rbd working for me.

Comment 4 Boris Ranto 2014-12-23 12:32:01 UTC

Thanks for testing, closing as duplicate of the bz.
