Renicing the guest you want to give more priority to is a straightforward way of boosting the priority.

Can you mention what kinds of stats you're looking for? Since each guest is a normal process, a lot of information can be already examined by ps, top and /proc/<pid>/... There also is the kvm_stat that comes with the kvm-userspace which lets you monitor guest exits into the host. Those are mainly for debugging purposes though. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
