[RFE] Can not disable Host to VM affinity rule
Last modified: 2018-05-15 13:50:39 EDT
+++ This bug was initially created as a clone of Bug #1493149 +++ Description of problem: Once enabled "host to VM" affinity rule under affinity group cannot be disabled. Version-Release number of selected component (if applicable): rhevm-4.1.6.2-0.1.el7.noarch How reproducible: Always Steps to Reproduce: 1. Create affinity group with host to VM affinity enabled <affinity_group> <name>test</name> <enforcing>true</enforcing> <hosts_rule> <enabled>true</enabled> <enforcing>true</enforcing> <positive>false</positive> </hosts_rule> <positive>true</positive> <vms_rule> <enabled>true</enabled> <enforcing>true</enforcing> <positive>true</positive> </vms_rule> </affinity_group> 2. Disable "host to vm" affinity rule <affinity_group> <hosts_rule> <enabled>false</enabled> <enforcing>true</enforcing> <positive>false</positive> </hosts_rule> </affinity_group> 3. Actual results: <affinity_group href="/ovirt-engine/api/clusters/00000002-0002-0002-0002-00000000017a/affinitygroups/a2cdfe24-5087-4d09-a02d-7cfb9a3d43b3" id="a2cdfe24-5087-4d09-a02d-7cfb9a3d43b3"> <name>test</name> <link href="/ovirt-engine/api/clusters/00000002-0002-0002-0002-00000000017a/affinitygroups/a2cdfe24-5087-4d09-a02d-7cfb9a3d43b3/vms"rel="vms"/> <enforcing>true</enforcing> <hosts_rule> <enabled>true</enabled> !!! not updated !!! <enforcing>true</enforcing> <positive>false</positive> </hosts_rule> .... Expected results: Host to VM affinity rule must be disabled Additional info: Bug actual for REST and UI --- Additional comment from Martin Sivák on 2017-10-12 07:35:35 EDT --- This is not supported, host affinity is always enabled. You can only disable it by deleting the rule. --- Additional comment from Roman Hodain on 2018-03-29 04:27:23 EDT --- This is very confusing as the WebAdmin allows the user to disable the affinity for the hosts. It just does not persist the state. To me, it rather feels like the disable state should be the same as not filling the list of the hosts. Because if you do not set any hosts the force the VMs to run out of any host or force them to run on any. That is from the user perspective. Not talking about the implementation. What do you think Martin?
This has already been fixed as part of different bug.
(In reply to Martin Sivák from comment #1) > This has already been fixed as part of different bug. Can you please give more details? Does this mean, it will be possible in RHV-4.2 GA?
Yes, we believe it should be working as expected there. QE might want to verify that though before we pronounce it fixed.
Sounds great, thanks. One more thing, are the bits already included in rhv-4.2 beta-3?
verified on rhv-release-4.2.3-2-001.noarch steps for reproduce are performed by both - UI and Rest. Step1. POST https://{{host}}/ovirt-engine/api/clusters/de53e75b-b4b0-4252-9e94-af5098c45325/affinitygroups <affinity_group> <name>test</name> <enforcing>true</enforcing> <hosts_rule> <enabled>true</enabled> <enforcing>true</enforcing> <positive>false</positive> </hosts_rule> <positive>true</positive> <vms_rule> <enabled>true</enabled> <enforcing>true</enforcing> <positive>true</positive> </vms_rule> </affinity_group> Step2. PUT https://{{host}}/ovirt-engine/api/clusters/de53e75b-b4b0-4252-9e94-af5098c45325/affinitygroups/4bd31a35-d3eb-4be5-b266-c880e9104a8c <affinity_group> <hosts_rule> <enabled>false</enabled> <enforcing>true</enforcing> <positive>false</positive> </hosts_rule> </affinity_group> Result: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <affinity_group href="/ovirt-engine/api/clusters/de53e75b-b4b0-4252-9e94-af5098c45325/affinitygroups/4bd31a35-d3eb-4be5-b266-c880e9104a8c" id="4bd31a35-d3eb-4be5-b266-c880e9104a8c"> <name>test</name> <link href="/ovirt-engine/api/clusters/de53e75b-b4b0-4252-9e94-af5098c45325/affinitygroups/4bd31a35-d3eb-4be5-b266-c880e9104a8c/vms" rel="vms"/> <enforcing>true</enforcing> <hosts_rule> <enabled>false</enabled> <enforcing>true</enforcing> <positive>false</positive> </hosts_rule> <positive>true</positive> <vms_rule> <enabled>true</enabled> <enforcing>true</enforcing> <positive>true</positive> </vms_rule> <cluster href="/ovirt-engine/api/clusters/de53e75b-b4b0-4252-9e94-af5098c45325" id="de53e75b-b4b0-4252-9e94-af5098c45325"/> <hosts/> <vms/> </affinity_group>
