Hi, in relation to the changes shown here : ( , I want to set cpuset attribute. But I can't enable this. I tried to add vcpu_pin_set to nova.conf , but it's not working. I am using devstack on Ubuntu 12.04. What am I doing wrong?

is there any way to pin cpus dynamically? I believe there is no way to do this, currently the vcpu_pin_set affects all instances.

Peeyush Gupta confirmed that the question is solved: Hi wangpan, sorry for replying late, I was busy with some other stuff. I tried it out and guess what, it's working! Thank you very much! One more thing, is there any way to pin cpus dynamically? Meaning that when I give "nova boot" command can I decide which cpus I am going to pin this particular VM and the result reflects in the VM's xml? Does this mechanism works for each instance or just for making groups for libvirt to use?
