I've been wrestling with this all night, digging through various bits of
VDSM code trying to figure why and how this is happening. I need to make
some templates, but i simply can't.
VDSM <host> command HSMGetAllTasksStatusesVDS failed: value=low level

Following the VDSM logs, i can see the new image gets created,
permissions set, etc... but as soon qemu-img starts, it fails like this.
I updated all hosts and the engine, rebooted the entire stack, to no
avail. So i detached the storage domain, and wiped every host and fresh
installed both engine and all nodes, imported the storage domain, and
still no dice. Storage domain is gluster volume, single node, created in
ovirt.
It happens when i make a template, copy an image, or make a new vm from
a template. I can still create new vms from blank, and upload images via
the web ui. Watching the gluster share, i can see the image being
created, but its deleted at some point. I appears to not be being
deleted by the template / copying process, as immediately after the
above error, i get this one.
VDSM command DeleteImageGroupVDS failed: Image does not exist in domain:
'image=4f359545-01a8-439b-832b-18c26194b066,
domain=b4507449-ac40-4e35-be66-56441bb696ac'

I thought maybe garbage collection, but don't see any indication of that
in the logs.
Any ideas? I redacted host names from the log output.
