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.
