Is there a way to define how much of the cpu a particular domU is

if it is available.
Hi Paul,

yes (of course), something like that.

There is the "memory" parameter in the domU's config file. This is the default as well as max RAM assigned to a domU at boot time. At runtime you can use "xm mem-set <domain> <megabytes>" to dynmically adjust allocated RAM, but only up to the initial value.

All this is accomplished via the "balloon" driver.
