I have shifted some VM's to a new server running Quantal
and have had a world of trouble. The first one was caused
by issues with an apparently compiled in path in their
apparmor version which forced VM pools to be in /srv or
similar rather than where I wanted them. For now this was
not a big issue
I have a better faster server and moved the disk from
the old one to the new one.
After the move, I edited the xml file manually to give
it the correct paths for the new machine, since the
mount point for all the VM storage pools is now different.
I get

I suspect the answer is no, as the very idea makes
my head hurt, but a confirmation would be nice:
Am I correct in assuming that it is a very bad idea
to mount a physical disk on both the physical machine
and on a hosted VM at the same time?
I can imagine getting away with it if one were RO, but
Some of the discussion items I have seen about
VM's failing under upgrades brings up a worrisome
point, for me at least.
I look at a VM as a 'forever machine'. A way in
which I can set up an environment with any old
OS and software and be able to boot and interact
with it now, or next year or 100
