CpuOverCommitDuration not working correctly in cluster policies
Last modified: 2016-02-10 15:14:48 EST
Description of problem:
CpuOverCommitDuration not working correct in cluster policies, also for Power_Saving and also for Even_Distribution policies, it's mean that if I have host with vm, that CPU of host out of define thresholds and I also have host that CPU of host in given bounds, vm start migration without waiting given in CpuOverCommitDuration field time.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Add two hosts to engine, add vm and run on one of host, change cluster policy
or to Power saving or to Even Distribution, I will describe reproduce process for Even Distribution, by default CpuOverCommitDuration is 2 min and HighUtilization on 80
2. Load host CPU with running vm to 85%(you also can try some script, to run infinitive loop)
Engine not waiting two minutes, but begin migration to host without loading CPU much earlier.
engine waiting given CpuOverCommitDuration time and just after this start migration if it still actual.
whole process loading CPU and waiting until vm will migrate on other host, takes less than minute
Created attachment 825069 [details]
engine and vdsm log
Verified on is28, vm migrate after given time.
Closing - RHEV 3.3 Released
