Re: [Xen-users] Xen Not Support multi-cpu??

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

Hi,

That info is out of date, Xen ha supported SMP guests throughout the 3.x 
series, so it should work fine for you.

It's normal to run dom0 as a UP guest though, since this is often only used 
for IO.  Dedicating a core or hyperthread to it can improve performance.

Cheers,
Mark
