[Xen-users] Question on CPU usage

[Simon Hobson <linux@xxxxxxxxxxxxxxxx>]

I have looked but not found anything in the docs - if I've been blind 
then just say so and point me at the right place !

If I have a 4 core machine, and run 5 Dom-Us, each configured to use 
one processor, how does Xen manage Dom-processor mapping ?
Does it dynamically assign Dom-Us to processors based on current load ?

Or is the assignment static and dependent on what order they are 
started up ? Eg, the first three will get a core each, but the last 2 
will share one - or some variation.
And does this change if one or more Dom-Us are configured to use 2 processors ?
