Re: [Xen-users] SMP support in Windows domU

["Jordi Segues" <jordisd.mailing@xxxxxxxxx>]

Hello again,

I've spoke too fast, sorry :)
After some tests, I finally have a Windows XP HVM guest running with 2 vcpus.

I set it in the config file, and then installed windows with that config file.
After the final reboot, windows says he have upgraded some features
and that he needs a reboot to apply them.
After the reboot, it detects new "hardware" with the little icon at
the right with the "acpi" label.
Then, doing a CTRL-ALT-SUP, I see 2 CPUs in the task manager/Performance.
That's all :)

I've tested with a 1 vcpu install too, upgrading it to 2 vcpu then in
the config file, and I seems not to work, for the moment.

Sorry again.

Cordialy,

Jordi.S
