Mats, thanks for fast answer...

...at lest some concretes. 

I want to try openSuse 10.3 alpha3 witch port Xen 3.0.5 only to try that
increase the XEN release version is the good direction.

Generally I try to find some person that successfully run Windows with
more than one working VCPU, and can answer "It work on my machine, on
Linux XXX, Xen version X.X.X.X", because for now I don't find in the net
such "declaration".

> 3.0.3, I don't believe has any improvement on the SMP-guest
capabilities, > but there are some other improvements in the HVM support.

I was half successfully run the Windows with two VCPS working with acpi=1
and apic=1 and vcpus=2 on mentioned XEN 3.0.3 version. Here is the
scenario how the guest behave (for this ones that will try to the same as
me) :
1. Booting install CD, partition disk, copy required files, rebot.
2. Booting form HDD and when the splash show the 'xm vcpus-list' inform
that my quest using both VCPUs. But whne the progress bar is shown and the
text 'installing drivers' it's hang.

If I found or herd that someone have "physical" success with this issue my
hope, to run the environment as I wont, will grove dramatically. For now
is good to hear that the 3.0.4 version support SMP ACPI...so I go to try
it, but still waiting for somebody that write the sentence mentioned
before :).

Best, Bart.
