If I try to start my Linux dom0 with more than than about 800M it won't

memory architecture?  Also how do I get a a xen dmesg from the previous

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.
