I have heard in the past it used to be suggested 2x ram for swap but that much is not often needed. In general a dom0 should not require so much ram because it doesn't as a rule do anything but serve domU's. 128 megabytes of each should be plenty.Alas! The RHEL 5 and thus the CentOS 5 Dom0's fail to run virt-install or virt-manager without at lest 500 Meg of RAM available for Dom0. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
