[Xen-users] How Many domUs on a Host

[Mohammed King <mohammed.king@xxxxxxxxx>]

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
