Didn't find much about the maximum number of DomUsin the list archives... The Dom0 is running a CentOS4 x86_64 and I don'teven need a DomU image to reach this limit, network and diskless DomUs just running into an "no root filesystem" panic being "preserve"d after the crash have the same effect. Xen's own private heap is fixed size (16MB) and that's used to allocate a certain amount of per-domain state. This restriction could be lifted on x86/64 but it's not particularly a priority right now. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
