I left space when setting up my Xen server so I could create the logical
volume to hold recordings (my dom0 volume is about 30GB ...
the drive is 750).  I actually just completed my backend migration about an
hour ago... had to do the copy of recording files overnight.
When I've completed migrating things off the hold hardware, I'm actually
going to move the old disk into the new box, reformat, present it to the
mythbackend domU and move my recordings back so I can free up the LV space
for other purposes.  The DB backup and restore worked like a charm
(remembering to run the change hostname command of course).  I'm now working
on upgrading my frontends...
fingers crossed.  If you don't have space in your mythbackend domU, you
could conceivably copy the files to another domain that has space and do an
NFS export?

I attempted to move my masterbackend to a xen domU as well a few years ago
and succeeded with one issue. The recordings got messed up because of write
speed issues to the "drive" I was using. I setup a NFS share on the dom0 and
mounted that inside the domU. Multiple simultaneous recordings oversaturated
the virtual nic and caused data corruption.
My recordings now all exist on a separate RAID drive that I could
potentially put inside the bottle, but my capture devices do not all live on
the system anymore. I have an HDHRPrime and a slave backend with an HDPVR.
If both of them were to be recording on all tuners I could run into a
similar issue.
I may attempt again at some point in the future, but I need a motherboard
with 2 NICs so one could be dedicated to the domU.
