XO / Migration issue

Danp

I know there are a bunch of XO users here. I would appreciate it if you could take a look and see if you can replicate the issue described here.

Thanks, Dan

From Github:

After migrating a VM, a "ghost" VM is shown in XO. This VM doesn't appear in XC, and it goes away after restarting xo-server.

I don't have two hosts to try on, but I did notice that when you import a VM creates what looks like a second temporary VM during the import. It disappears once the import is completely done. Not sure if these two things are related or not.

NTG Lab would be nice for testing this

Yeah... it's like the temporary VM is being "cached" by XO until you restart xo-server. Since @olivier can't reproduce it, I thought someone here could try testing it for me.

Anybody willing to give this a go?!

I'm actually not running XO/XS anymore... switched over to KVM due to other issues.

I would if I had more than one host.

Made around 50 migrations today, no issues, but I'm making mainly those tests on next-release. I really can't explain why this "duplicate" VM is appearing with an UUID coming from nowhere...

Does a temporary VM with a new UUID get created just prior to the final movement of the VM from one pool to another? This is what I'm seeing and this VM is what remains as the "ghost" once the migration is complete.

P.S. I recently tested this on 'next-release' and the observed the same thing.

Danp

@olivier FWIW, I just retested on the latest next-release with the same results. If I disconnect / reconnect the server from within XO, the "ghost" VM is now gone.
