I use the second option right now on my NetBSD dom0s it
works just fine
on NetBSD. I wouldn't use files if my Dom0 was anything but
NetBSD... the file-backed vbd stuff is supposed to be pretty
slow on
Linux- someone did a benchmark back in the Xen 2.0 days and
the
difference between NetBSD and Linux was radical.
I will likely be moving to option 1 in the future, as linux
software raid
sucks, and I have Linux Dom0s now- also I want live
migration to work
and that doesn't work if you do raid in the dom0
