libvirt users - Jul 2013 - Re: API to set cpuset.cpu_exclusive flag

Hi all,

I have been trying to set cpu_exclusive flag. Now I can do it using
"echo". I want to know is there any other way (an API) to set this
flag? Is it possible to set this flag using API?

Thanks.

There's no API in libvirt for setting this, and I don't really see the
point in this cgroup setting at all. It doesn't offer any critical
functionality that you can't achieve by just explicitly configuring
cgroups to not overlap.

I guess it could be helpful. I mean I wont have to do it through
virsh/echo/explicitly everytime. If I have an API for cgroup settings, I can do
it easily through my code.
 
Thanks.
