About add-support-for-cpu-hotadd
I'm interested in Openstack cpu hotadd, I found Openstack wiki about cpu hotadd(https://wiki.openstack.org/wiki/Nova/add-support-for-cpu-hotadd).
I follow first step:
Add extra key to flavor to define the instance's current CPU key:"cpu:current" value:"2"
I do this command: nova flavor-key cpu set cpu:current=2
and then second step:Create VM with max VCPU in flavor.
The instance's XML looks like:
< vcpu current="2">4 </vcpu>
so I create instance with this flavor. But instance's xml not<vcpu current="2">4</vcpu> but <vcpu>4</vcpu>
Does anyone finished vcpu hotadd?
Thanks!
