Hi,
I am using Xen 4 under Debian Squeeze. I want to use Windows 2008 x86
with HVM, but only one vcpu allocated when vm started.
After increasing vcpus number (vcpus = '4') in cfg, at start ignored
that parameter, xm list VCPUs show only 1.
Why does not able to increase the vcpus? Any idea?:)
p.s: if using pvm linux, then the vcpus parameter is ok, increased
successfully when I set it.
