[Wolfgang Hennerbichler <wolfgang.hennerbichler@xxxxxxxxxxxxxxxx>]

hello again,

after upgrading to folsom nova-compute dies the fabulous death while
gaining information from qemu-images.

the information-gaining process works for some images, and then we reach
the image instance-0000005c, which also has a snapshot associated with it.

let's see the difference:
regular image file:

qemu-img info instance-0000005d/disk
image: instance-0000005d/disk
file format: qcow2
virtual size: 4.0G (4294967296 bytes)
disk size: 3.0G
cluster_size: 2097152
backing file:
/var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_4
(actual path:
/var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_4)

and now an image with a snapshot:

computeNode1:/var/lib/nova/instances# qemu-img info instance-0000005c/disk
image: instance-0000005c/disk
file format: qcow2
virtual size: 2.0G (2147483648 bytes)
disk size: 1.8G
cluster_size: 2097152
backing file:
/var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_2
(actual path:
/var/lib/nova/instances/_base/cd906f63b4de02c79d87a328c79f3a988059e51a_2)
Snapshot list:
ID        TAG                 VM SIZE                DATE       VM CLOCK
1         d9a9784a500742a7bb95627bb3aace38      0 2012-08-20 10:52:46
00:00:00.000


the image with the snapshot kills nova-compute as we can see here:

help is appreciated. I wonder if it was wise to upgrade to folsom...
