Description

tentatively planned for 3.6 depending on support in QEMU and libvirt libvirt side in progress, https://www.redhat.com/archives/libvir-list/2015-May/msg00580.html this may be a late delivery As per last update from libvirt developers, support will most likely slip to 7.3, so we cannot implement this. as per last comment moving to 4.0 due to platform dependency Moving to 4.1, as platform bug 1181659 is not yet approved for 7.3. This request has been proposed for two releases. This is invalid flag usage. The ovirt-future release flag has been cleared. If you wish to change the release flag, you must clear one release flag and then set the other release flag to ?. (eventually) moved to NEW because I can't work on this until we have the libvirt support available. Moving back to ASSIGNED, as attached patch was abandoned. this is now completed and enabled by default Was tested and verified in performance environment and seen a good improvement : Lab Topology System topology (using bare metal hosts) 3 DC 5 Clusters 235 Hosts Hera : 4 Hosts leopard : 2 Hosts Nested hosts : 229 VMS 3 SD 1020 VMS Hera : 690 VMS leopard : 330 VMS Scenario matrix Delta between the tests Test Step Old New Build 06.12 Delta in HH:MM:SS Delta in percentage VM Stop 0:00:08 0:00:06 -0:00:02 -25.00% VM Start 0:00:36 0:01:00 0:00:24 66.67% Create VM From template 0:01:09 0:01:21 0:00:12 17.39% Nested Host stop 0:00:34 0:00:27 -0:00:07 -20.59% Nested Host start 0:00:50 0:00:30 -0:00:20 -40.00% Create Nested Host from template 0:01:17 0:01:15 -0:00:02 -2.60% Sent maintenance to 10 hosts 0:00:08 0:00:07 -0:00:01 -12.50% Reboot 10 nested hosts 0:05:15 0:05:25 0:00:10 3.17% Reboot 50 nested hosts 0:05:57 0:05:46 -0:00:11 -3.08% Reboot 80 nested hosts 0:10:35 0:10:34 -0:00:01 -0.16% Reboot 100 nested hosts 0:15:09 0:11:40 -0:03:29 -22.99% Engine restart 0:00:47 0:00:55 0:00:08 17.02% This bugzilla is included in oVirt 4.2.0 release, published on Dec 20th 2017.
