Hi guys, Looking for some guide lines to find out how many domUs I can host on a server. I have a Dual Quad Core (8 cores) server with 32GB of RAM. Currently I have allocated 512MB of RAM to dom0 and distributed the rest to 89 domUs with 1 VPU each and LVM as my backend. I was able to get all 89 running with no problems. I ram some test with stress and bonnie++ in a group of domUs and dom0 and other guests does not seam to be effected. However, I could be evaluating this incorrectly. Are there any tools or guidelines to confirm these results or do better performance analysis? My main concern is I/O and CPU usage. Thank you -- Mohammed King Systems Administrator ---------------------------- No condition is permanent _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I run 42 interactive gui sessions on a very similar machine and it''s pretty well tapped. Grant McWilliams Some people, when confronted with a problem, think "I know, I''ll use Windows."
