Bug Description
Noticed in OpenStack Mitaka (commit 9825c80), but the function (snapshot_
When Nova attempts to create an image / snapshot of a volume-backed instance it first quiesces the instance in `snapshot_
In my case, the steps for reproduction are:
1) nova create image / ( "create snapshot" via horizon )
2) nova/compute/api snapshot_
3) "qemu-ga: info: guest-fsfreeze called" is seen in instance
4) cinder fails snapshot of volume due to OverLimit
5) cinder raises OverLimit
6) snapshot_
7) filesystem is never thawed
8) instance unusable
I am in the process of writing and testing a patch and will have a review for it soon.
