Hi James,

Thanks for the response.
Unfortunately, "xm start" is not helping me either.

Should I reboot dom0 to get this working ?
I would like to keep it the last option to try as am facing
other issues immediately after the dom0 reboot.

Any other tricks to get multi-core working with Windows ?

BTW, I could not find "xe" command in my XEN installation.
Even after installing the "xe-cli" rpm file, it is failing
Consistently with the error message :

"Error: Connection refused (calling connect )"
