[Xen-users] How to set Domain-0 VCPUS in Ubuntu 12.04

["qy610426@xxxxxxx" <qy610426@xxxxxxx>]

Hi,

    I try to pin cpu cores for Domain-0,I use Ubuntu 12.04 ,xen 4.1.5. according to this article  "Tuning Xen for Performance"

    1. I change the file "/etc/default/grub":

    

GRUB_DEFAULT="Xen 4.1-amd64"

#GRUB_HIDDEN_TIMEOUT=0

GRUB_HIDDEN_TIMEOUT_QUIET=true

GRUB_TIMEOUT=2

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

GRUB_CMDLINE_LINUX_DEFAULT="dom0_max_vcpus=4 dom0_vcpus_pin"

GRUB_CMDLINE_LINUX=""

    2. and then I run "update-grub" and reboot the system,

    3.when the machine startup,I used "xm vcup-list":

root@(none):~# xm vcpu-list

Name ID VCPU CPU State Time(s) CPU Affinity

Domain-0 0 0 7 r-- 14.3 any cpu

Domain-0 0 1 2 -b- 15.9 any cpu

Domain-0 0 2 0 -b- 13.2 any cpu

Domain-0 0 3 5 -b- 8.1 any cpu

Domain-0 0 4 1 -b- 9.7 any cpu

Domain-0 0 5 4 -b- 7.5 any cpu

Domain-0 0 6 3 -b- 12.1 any cpu

Domain-0 0 7 6 -b- 5.7 any cpu

vm01.test.yao 1 0 7 -b- 0.1 any cpu

     

     "dom0_max_vcpus=4 dom0_vcpus_pin" dosen't work?

      and how to  do my wants?

      someone plz help me
