Thread-topic: [Xen-users] Getting Windows 2003 to run in multiple cores ???
> Hi,
> Installed Windows 2003 on XEN successfully (domain name : win1).

This may not be your problem, but one thing that caught me out early on
is that if you make a change to the config file and then do a 'xm
reboot' (or just do shutdown->restart in windows), the change isn't
picked up - it runs with the old config. You need to shut down the DomU
and then 'xm start' it.

Another thing, on the first startup after changing from vcpus=1 to
vcpus=2 (or more), Windows needs to install the SMP HAL so it will say
something like "your hardware has changed and you need to reboot for the
change to take effect".
