Cannot compose VM in MAAS UI (again)

[Rajko Albrecht]

As in ticket 1951842 described: I can't create vms on a LXD host.

I setup the lxd host like described, integrated into maas but when I try to create I just get error messages that memory and CPU count has to be less or equal to zero. I tried multiple times to refresh, the values about memory and CPU count are listed correctly in UI, running VM from command line works. MAAS correctly reads in all resources (CPU count, memory, storage). MAAS is version 3.3.

The only related messages in logs are below. I didn't see any other messages.
