I've found that the first export attempt always fails, but subsequent exports tend to work afterwards. Although, it resets after a time. I'm not sure if this is authentication related or not, but it only seems to work for about 24 hours.
The easiest way to check that I've found is: 1. Make the initial export and let it finish. 2. Discard that initial export. 3. Export the VM again. 4. Try to archive it. (tar -cvJf a.tar.xz a.ova) 5. Check the file size of the archive, if it's greater than a couple MB you're probably fine. (Do try to import it back and use it, if you want to be sure.) If not, go to step 3. It's definitely a pain, but the alternative would be to boot some other VM and run a clone of the original. I've used FOG in the past for this and it works fine even on the same hypervisor host. (Writes the disk images to a NFS share or local filesystem) But you could use anything. Others here have used Clonezilla. If you have a tape drive or some other external backup device you could pass it through to another VM and use it to write the backup directly. Also, as a sidenote: oVirt 4.4 uses a newer imageio proxy that only seems to work with Chromium based browsers. So don't try using Pale Moon, Waterfox, etc. with it as you'll always get bad exports and failed uploads. I had to find out the hard way. - Patrick Hibbs On Mon, 2022-02-21 at 19:34 +0000, Abe E wrote: > So as title states I am moving VMs from an old system of ours with > alot of issues to a new 4.4 HC Gluster envr although it seems I am > running into what I have learnt is a 4.3 bug of some sort with > exporting OVAs. > > Some of my OVAs are showing large GB sizes although their actual size > may be 20K so they are showing no boot device as well, theres really > no data there.
