Hi i recently added a lxc compute node to my Openstack Queens enviroment running in Ubuntu 18.04. When i try to deploy an instance in this compute node i'm getting this messages

2019-03-08 16:13:58.022 2438 WARNING nova.virt.libvirt.driver [req-78f6ee93-7554-48c0-9ed9-8457b674347c a16c6ef0319b4643a4ec8e56a1d025cb 59065d8f970b467aa94ef7b35f1edab5 - default default] [instance: e6bd1d65-f77c-482e-bda5-31df539b3e06] Ignoring supplied device name: /dev/vda.

I think i have a problem with the name of the block device Libvirt is using for the instance, and because of that it is failing to spawn.

Any idea how can i fix this trouble??

This has been an issue for a couple of years now, see this bug I reported a while back. The comments in the bug also describe some workarounds, I'd recommend to read all of it, but maybe start trying the patches from the bottom first.
