Hello,

I'm trying to figure out why some of our VMs won't snapshot successfully. It's working for half of them; the only difference that I can see between those that snapshot and those that won't is that the HD is a bit bigger (160gb vs. 80gb), but that's it...

Full output:

snapshotting 'drive-scsi0' (local:100/base-100-disk-0.qcow2/101/vm-101-disk-0.qcow2)
snapshot create failed: starting cleanup
TASK ERROR: VM 101 qmp command 'blockdev-snapshot-internal-sync' failed - Need a root block node

Any suggestion how we can troubleshoot this?
