I don't know how much experience with kernel issues you have, but I would
take the EIP from the CPU0 guest dump in that log file (the EIP is c01edc67)
and look at that code address in a disassembly of the dom0 kernel image
(objdump -d vmlinux). Seeing what function you're in would be a good start.
'addr2line -e vmlinux c01edc67' would also be useful: tells you the source
file and line number.
