Thanks for the info - I'll look for the update. I still get the panic, regardless of
memory settings.

OK. This crash is a bug in the 4.5 kernel that I've now fixed. It should be
fixed when 4.6 comes out. In the meantime, you probably should be able to work
around this bug by reducing the amount of memory you are assigning to that domain.
