That is correct, Dom0 doesn't seem to grow back. An "old-school" type, like myself, is also reassured somewhat, by allocating only what dom0 would only ever need - net services, compiling, running programs, etc. is isolated to domu's. Then, in the event dom0 is ever compromised (though very highly unlikely), or even if I accidentally start something there, dom0 can't take memory away - a DoS prevention, of sorts... jerry -- "Pay no attention to that man behind the curtain!" _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
