Unable to convert VM to Template in Xen Orchestra ( VBD_IS_EMPTY )

brodiecyber

Hello

Ive created a VM that Im converting to a template in Xen Orchestra (xo-server 5.113.0) but i get the following error.

The storage of the vm disk is an nfs share from TrueNAS scale mounted to a 3 node XCP-ng 8.2 cluster

I will note that i can convert to template in XCP-ng Center with no error.

My logs for the error is as follows

vm.convertToTemplate

So the conversion doesn't work?

To me, it's probably a stupid bug after we added a CD eject from template conversion. For the sake of testing, can you insert an ISO into the VM and then try to convert it into a template?

olivierlambert

I'm pretty sure it's a case we forgot to check. See https://github.com/vatesfr/xen-orchestra/pull/6769/files

Since @julien-f is AFK, @pdonias could we fix this?

@olivierlambert Morning i will clone the same VM and try to conversion with an iso installed.

Will update this post in the next few hours

@olivierlambert

Conversion in Xen orchestra works with the clone of the VM and the guest iso installed

olivierlambert

Julien will release a fix in master soon

@brodiecyber I've had this issue also. I found another workaround for this is to create a snapshot of the VM then convert the snapshot to a template . This worked without any ISO mounted.

olivierlambert

I think this is fixed now
