Yes, suspend/resume (and hence migrate) do not work (you may have some 
luck if you don't have any vifs attached, but that's hardly useful in 
production). I've been moaning about this for a number of years. There's 
no way for the domU to say it can't do suspend/resume, so you need to be 
really careful when using NetBSD on, say, XenServer when applying 
automated patches as it will try to migrate VMs around to evacute hosts 
for reboot.
