Description Yaniv Lavi 2014-12-30 12:25:48 UTC
+++ This bug was initially created as a clone of Bug #1177790 +++

Description of problem:
Locality improves VMs performance. This feature is to add parameters and policies to oVirt scheduler to optimize VMs performance on hyper converged nodes.

This includes:
1. scheduling of disk creation in the best order for running VMs.
2. scheduling of the VM tun based on disk locality.
3. Get image replica set that is needed for scheduler.
4. Force image on a replica set in order to provide the best performance.

Comment 1 Niels de Vos 2015-01-06 13:19:55 UTC
It is possible to get the bricks (and therefore servers) where the image (file) is located. There is an extended attribute that can be read by privileged processes to retrieve it.

It is also possible with some special notation (appending a @<something> to the filename?) to force creation of the file on a specific sub-volume (replica set).

The DHT/distribute folks can probably explain the details.

Comment 2 Doron Fediuck 2015-08-26 14:12:54 UTC
Since this is about ovirt scheduler, updating relevant components.

Comment 3 Red Hat Bugzilla Rules Engine 2015-10-19 11:01:54 UTC
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.
