Well, for example it's not really going to work with the default memory allocation policy where dom0 takes all memory and then auto-balloons itself down as domains are created. In this situation the domU will end up with whatever dom0 happens to have freed up: there's no guarantee of locality. I don't think that auto-ballooning is a particularly sensible setting for serious use of Xen. I'd always advise to work out how much memory your dom0 actually needs and make that a static allocation at boot time. But it is our out-of-the-box default: another thing that needs explicit changing (via dom0_mem= in this case). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
