Support
#1

Problem:

Clicking edit on libvirt hosts produces: Oops, we’re sorry but something went wrong undefined method `persisted?’ for nil:NilClass

Expected outcome:

Should proceed to the edit screen

#3

This is only for existing libvirt hosts, new ones can be created and edited. The ones with the issue report the error “Failure: undefined method `allocation’ for nil:NilClass” when trying to select the VM info tab. What would be the best way to fix?

Foreman’s libvirt compute resource is VERY limited, it would not work for VMs created outside of Foreman. Libvirt is an extremely open API with very complicated interface (ton of XML) and possibilities are huge. Foreman can only handle basic storage and network domains (directory with images, NAT network).

If you enable debug there should be a stacktrace that should help us to identify the line, to me it looks like the volume is not loaded correctly, is nil thus vol.allocation raises exception. There is not much we can do other than improve the error message.

#6

I’m hitting a similar issue trying to “manage” compute infrastructure and VMs created outside of Foreman. While I understand your point, here, in my use-case I would like to bring into Foreman management several libvirt-based compute resources that were previously deployed. If there are steps that need to be taken to make these resources “Foreman-ready”, it would be nice to have those - I’m not opposed to making changes to make it work, but I don’t necessarily want to go through and re-deploy everything through Foreman that is already running.

Here’s what I have from the /var/log/foreman/production.log file - not sure if this helps anymore than what @twh already posted??

This only confirms what I thought, volume is nil, that domain is not compatible with Foreman.

#8

When you say “volume is nil”, what does that mean? Or, perhaps more precisely, what item is missing from the domain’s XML configuration that Foreman is expecting to find? How do I go about making the domain “compatible”?

#9

Create a VM through Foreman, then compare the libvirt’s domain XML (virsh edit VM) with the one which fails. It needs to be exactly the same (except the data like VM name, memory size, UUID etc). That is what Foreman “understands”, anything else will typically cause Foreman to raise an exception.

#10

We hit this, and doing some very quick investigation, at least for us on storage, it is an issue in fog (https://github.com/fog/fog-libvirt/pull/117) and also mentioned in #34479 (Bug #34479: fog-libvirt change not being handled in the template - Foreman). I haven’t tested the fix but it aligns as we have some volumes using dev.
