SMP and Xen

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

I have a dual-processor machine I'm using for Xen.  A few questions...

First -- is it safe to use SMP with Xen?  I've heard contradictory
opinions on this.  This is Xen3.0.3 on 4.0beta2.

Second -- should my Dom0 see both CPUs?  Currently, it does not.

Third -- is there any performance benefit to setting 'vcpus' to 2 (for
a DomU that would benefit from that)?  That is, will a DomU actually
run on more than one CPU?
