[RESEND PATCH 0/2] migration: Report migration related thread pid to libvirt to support migration pin

Posted by Jiang Jiacheng via 1 year, 3 months ago

By default, the migration thread shares CPU resources with the VM process. 
With migration pin, support pin migration thread to expected CPU list 
to avoid preempting CPU resources of VM process.
To support migration pin, we need report migration related thread pid 
to libvirt.
