RE: [Xen-users] pin cpu 0 to dom0.

["Robert Dunkley" <Robert@xxxxxxxxx>]

Hi,

First try setting the option in xend-config:
vi /etc/xen/xend-config.sxp  -  set “(dom0-min-mem 0)” and set “(dom0-cpus 1)”

You might also need to fix the Dom0 Ram:
dom0_mem=2048M (Put this in the kernel boot line)

Subject: [Xen-users] pin cpu 0 to dom0.

I'm using debian lenny with xen 3.2.
I want to pin cpu 0 to dom0.
My boot parameters are:

boot/vmlinuz-2.6.26-2-xen-amd64
root=UUID=56288354-501c-48e7-80c1-1870898edf61 ro console=tty0
clocksource=jiffies dom0_max_vcpus=1 dom0_vcpus_pin

but xm list still says:

Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0 13068    16

and xm vcp-list:

Name                                ID  VCPU   CPU State   Time(s) CPU Affinity
Domain-0                             0     0     2   -b-       9.5 any cpu

Domain-0                             0    14     3   r--       2.6 any cpu
Domain-0                             0    15     9   -b-       2.8 any cpu
