[Xen-users] BUG? XEN don't take all CPUS when "(dom0-cpus 0)" is set

[Fabian Holler <fho@xxxxxxxxxxx>]

Howdy,

i have Debian running + xen-hypervisor-3.0-i386/testing uptodate
3.0.2+hg9697-1 on 2 CPU machine.

If i set "(dom0-cpus 0)" in  xend-config.sxp, dom0 only will use one CPU
(only one CPU listed in /proc/cpuinfo).
If i set "(dom0-cpus 2)", dom0 will use both CPUs.

But in the example xend-config.sxp, there parameter is explained as follows:
"# In SMP system, dom0 will use dom0-cpus # of CPUS
# If dom0-cpus = 0, dom0 will take all cpus available"

Is this a Bug? Or what is the reason why dom0 don't will take both CPUs
if dom0-cpus 0 is set?


greetings

Fabian
