I don't have any of these in the kernel command line of my Tumbleweed host.

Interesting. Can you start your containers if you remove the above kernel
options, but enable DefaultMemoryAccounting as described in the following bug
comment?

BTW, I reproduced virtlxcd terminating after 2 minutes even with a running
container. I'll need to investigate further. However, in my case the container
did continue to run, although it's quite simple
