As far as I can tell, for Xen 3.1 (3.3 should not differ much - I can't 
test it, due to missing PAE support in dom0):

- for a netbsd dom0:

mem-set/mem-max: not supported (no balloon driver in netbsd yet)
save/restore/migrate: should work with a very -current kernel, provided 
domU supports it
vcpu-*: not supported (no SMP support in port-xen)
ACPI: not supported

- for HVM domU:

I do not know precisely, YMMV: depends on qemu-dm code, and how the 
virtualized OS behaves.

for netbsd PV domU:

mem-set/mem-max: does not work (missing balloon)
save/restore/migrate: working on it, it is not in tree. Experimental, 
works somehow.
SMP: not supported.
