I''m having a hard time understanding how to determine load on my domUs. I''m running FC5 on both my dom0 and domUs, all up to date against the official fedora repositories as of last night. On at least one of my domUs acting as a database, xm top shows CPU load at roughly 60% when I fire off some long-running queries. That sounds reasonable to me, but running top of the domU itself shows almost no cpu load. The domU *is* doing a lot of I/O, but according to vmstat on the domU, very little of the processors are stuck in I/O wait state. So, I''m not sure what the proper question is. It''s probably some combination of these two: 1. Why does the domU not think it''s stuck in I/O wait? 2. Why does xm top and top on the domU disagree?
