Hi all !

We are making our first steps under Xen. We are working under Suse,
and we successfully installed 4 virtual machines on a Core2Duo T7200.

We have some special performance needs, so the first thing we tried is
to share, on different configuration, CPU usage.

To "touch" the results, we simply run nbench [1]

The problem is that we always have the same final result, even in the
following configurations :
- nbench running only on Dom0
- nbench running on 4 VM, each one has 1 VCPU (each VM is "any cpu")
- nbench running on 4 VM, each one has 1 VCPU (first VM in assigned on
CPU 0, the 3 others on CPU 1)
- nbench running on 4 VM, the first one has 10 VCPU, the other one
have 1 VCPU (each VM is "any cpu")

We really are getting crasy !!! Did we miss something ? How to be sure
to share correctly CPU consumtion ?

Thank you very much,

Regards,

gUI
