[et-mgmt-tools] [PATCH] BZ#251643: Allow to set the cpu pinning for to create installing domain

[Tatsuro Enokura]

Hi,

I want to set the cpu pinning for create installing domain by virt-install
on RHEL5.1.

So, I just add the option to virt-install.
We will be allowed to set "cpus" parameter in configuration file
and to set "cpuset" parameter in create installing domain with "cpuset" option
by this patch.

command-line example:
  # virt-install --name=domain1 --ram=512 --file=/dev/sdb --cpuset=0,2-4 ...

some notes are follows:
  - cpuset can only contain numeric, ',', or '-' characters.
  - cpuset's pCPU numbers must be less than pCPUs.
  - This is an effective feature for to create installing domain and
    configuration file with libvirt revision >= 1.789.
  - This is an effective feature for to create installing domain and
    configuration file with xen hypervisor.
    Other hypervisor(like kvm, qemu...) ignores this option.
  - This feature covers cpupin on virt-install of BZ#251643.
    It will work about other things(weight, cap, ...) in the future.
