Open Stack

hi,

after I've upgraded to folsom snapshotting just stopped working. Horizon
doesn't complain, the log doesn't complain, but the snapshot is
reportedly not taken (snapshot file isn't created, and I don't see the
process of qemu creating it).

as I said, nova-compute on the server doesn't complain:

Running cmd (subprocess): sudo nova-rootwrap /etc/nova/rootwrap.conf
qemu-img snapshot -c fd5ab4d51e12435884c8a90f190f1f15
/var/lib/nova/instances/instance-000000f3/disk from (pid=13330) execute
/usr/lib/python2.7/dist-packages/nova/utils.py:176
Result was 0 from (pid=13330) execute

from (pid=13330) execute /usr/lib/python2.7/dist-packages/nova/utils.py:176

any hints or suggestions? Our customers really want this feature.
