Hi list,

After setting up 4 DomU on my server. I decided to take my baby for a
ride. In one of my DomU I am installing Rails, and it takes for ever.
My server has a P4 3Ghz cpu, Dom0 has 600Mb ram and DomU has 528Ram.
Hard drive is Sata2.

When I type xentop I get:
Domain-0 Cpu > around 10%
DomU Cpu > 10-25%

In Dom0, when I type top, I get:
Cpu(s):  0.0%us,  0.0%sy,  0.0%ni, 98.7%id,  1.2%wa,  0.0%hi,  0.0%si,  0.2%st


My cpu is hardly used by DomU. Is there something to tweak for the cpu?
