RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #1114492 +++

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. It affects the scalability of RHEV and we are starting to see issues with the polling on big customer setups.

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.

We will have to backport a lot of staff to implement this feature and it would be too invasive for rhel 6.7.
