[libvirt] [PATCH 2/6] cputune: support cputune for xend driver
Didn't test it, and not sure if it's the correct way to add cputune
xml for xend driver, and besides, seems "xm driver" and "xen
hypervisor"
also support vcpu affinity, do we need to add support for them too?
Any suggestion on supporting cputune for xen is appreciated. :-)
