How about this as a plan?
(1) Add 'virsh savetuning' and 'virsh loadtuning' commands as Daniel Veillard has suggested above. These would save the per-domain tuning information to an XML file
<tuning> <pin vcpu="0" pcpu="0"/> <pin vcpu="1" pcpu="1"/> <!-- other stuff for cpu_weight, etc. --> </tuning>
Ok, looks fine to me.
(2) Modify 'virsh define' and 'virsh create' commands to add a '--with-tuning' flag, so that:
virsh define foo.xml --with-tuning foo-tuning.xml
Which basically does the ordinary 'virsh define' step followed by 'virsh loadtuning'.
I agree and I want to add '--with-tuning' flag to 'virsh start' command, too.
(3) Modify 'virsh save' to add '--save-tuning', so that:
virsh save foo foo.img --save-tuning foo-tuning.xml
This captures the tuning information into the XML file, and is the same as doing an ordinary 'save' followed by 'virsh savetuning'.
Sounds good to me. Thanks, Tatsuro Enokura
