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

Hello,
I've followed your conversation...
I'm trying too to run a windows hvm guest with several vcpus.
I've Xen 3.0.4 installed and recompiled on a Debian Etch, and all
works great, unless the SMP support in HVM windows guests.
In my config file I have:
....
vcpus=2
acpi=1
apic=1
...
But my HVM guest still don't detect 2 vcpus.
I've tried it after the windows install, and then I've reinstalled
windows with this config file, but nothing changes (thought windows
detects it at install time).
I've read a post in this mailing list (don't have the link) where
someone says that the hvmloader firmware must be recomplied
specifically. And I've understanded too that the recompilation is
static, so all the vcpus number of all hvm guests will have to be
identical.
I haven't tried to do this, but I thought that xen 3.0.4 offered this feature.
So like Bart, I would like to know if anyone have done it! :)
Anyone have an HVM windows guest running with 2 vcpus? and if yes, how?
Well, maybe the 3.1 release (3.0.5) will fix this, and maybe not,
cause everyone says "it should", but I can't find someone really doing
it. :)
Thank you very much!
And I would like to thanks Mats too, who's allways here, and answers a
lot of questions very clearly.
Cordialy,
