If you want to tie dom0 VCPUs 1:1 with physical CPUs then you can put
dom0_vcpus_pin on your Xen command line.
So then, when I do "xm vcpu-pin my-domain 0 1", it will pin VCPU0 in
my-domain to the second HT of physical CPU 1?

That would be great as it would be straight forward.

Enumeration order is not guaranteed across systems. This could be fixed by
sorting the processor info records after we've found them in the BIOS

Well I meant on the system I mentioned, which showed
without Xen.

I'll give it a try today.

Well, it doesn't do what I would have wanted it to. It just does
something like
xm vcpu-pin 0 0 0
xm vcpu-pin 0 1 1
xm vcpu-pin 0 2 2
xm vcpu-pin 0 3 3

So is there currently a way to see the processors in the same numeration as in Linux without Xen?
