Re: [Xen-users] xen only shows only ONE "cpu core"

[Steven Timm <timm@xxxxxxxx>]

Is this on the dom0 or domU.

If on the domU, what value of vcpus do you have
in the config file.

For what it's worth on my dom0 Xeon E5430 CPU running
xen kernel it shows 8 processor entries in /proc/cpuinfo
and shows each one of them with cpu cores : 1 too.
