Check how much memory you have free (from dom0) with "xm info" -- you
can't give more than that. Either reboot with less memory for dom0, or
ballon dom0/domU('s) down.

Can't get a xen dmesg from the previous boot, but you can look at the
current one with "xm dmesg". Of course you could script your dom0 to
save it with "xm dmesg > xen-dmesg.$number" on startup.

I'm surprised it won't boot at all. However, x86 Linux does require Highmem4G
support compiled in if it's going to use large memory machines: have you
compiled a dom0 kernel with this included (the binary distribution of the
xen0 kernel does not have this).

Cheers,
Mark
