Description Martin Sivák 2014-06-30 08:44:24 UTC 
Description of problem:

When multiple processes cooperate while managing a KVM/libvirt based virtual setup, they have to poll for changes in CPU and IO QoS settings.

Please add events so the processes (host manager and qos manager) can get the changed information in more efficient way.


This might apply to other values as well, but CPU and IO are the subsystems we care about the most at this time.
Comment 1 Cole Robinson 2014-07-02 14:04:48 UTC 
Moving to the upstream tracker.

Martin, if this is important to ovirt, I'd recommend filing a RHEL bug as well so resources are actually allocated as needed.
Comment 2 Peter Krempa 2015-03-09 13:28:22 UTC 
Upstream commits up to 42571dfa867acb89fea9a731f2e816005c9ab787 add the requested tunable change event.

This was released in libvirt-1.2.9.
