[Fedora-xen] CPU management

[Augusto Castelan Carlson]

Hi!

I will have servers with different CPU specification:
Quad core, dua core, one core.

Each core appears as one VCPU for xen?

How the management works when there is only one core, dual core and quad core?

Suppose that I have 2 guests and for the quad core processor I give 2
VCPU to the dom0 and one for each domU. How it is managed? If DomU
needs more CPU, it can use idle CPU from Dom0?  If DomU is using idle
CPU from Dom0 and Dom0 starts to need CPU, it will have their slice
back?

Thanks in advance.

Regards,
