} A quick test shows that it works with a NFS file. I don't know
} how stable that is.
It's documented as not working, and I know from experience
that it doesn't work, unless something has changed recently. My
test case, at least the most recent one from memory, has to do with
Xen. I keep ISO images on a NAS. I often want to feed an ISO
image to Xen when setting up a new domU or upgrading one. When
Xen is told to use a file for backing store, a script sets up a
VND and then uses that as Xen really wants a device. It doesn't
work when the ISO device is on a NAS, I have to copy it to the
dom0. BTW, the dom0 is running 6.1.5. I was just poking at it,
and may need to poke at it some more to try a couple of things.
