I sometimes see this in /var/log/messages:

Dec 21 03:17:01 vmx1 kernel: System RAM resource [mem 0x108000000-0x10fffffff] cannot be added
Dec 21 03:17:01 vmx1 kernel: xen_balloon: reserve_additional_memory: add_memory() failed: -17

Does this mean Dom0 is out of memory? Or a DomU is out of memory? 

How serious a problem is this? Would increasing dom0_mem on the kernel boot line help?
