I think its best to try and understand this before looking at the
crashes when starting new domains.
Running memtest is a good idea because your stock Debian boot
isn't actually exercising all of memory as its a non HIGHMEM
kernel on a 1GB machine, hence the top 100MB or so never gets
used.
Also, it would be useful to see the full output of Xen/dom0
booting. The memory detection happens early on, and its just
possible that the BIOS table parsing is failing (The Debian linux
kernel grumbles about pages being reserved twice).
