[jira] [Commented] (CLOUDSTACK-8713) KVM Power state report not
properly parsed (Exception) resulting in HA is not working on CentOS 7
[ https://issues.apache.org/jira/browse/CLOUDSTACK-8713?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14692971#comment-14692971 ]

---------------------------------------------
removing fixVersion from the bugs with empty assignee.

please update the fixVersion only when you plan to work on it or you know that someone is working on it. In that case, please update the assignee as well)

> Key: CLOUDSTACK-8713
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8713
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the default.)
> Affects Versions: 4.6.0
> Environment: KVM on CentOS 7, management server running latest master aka 4.6.0
> Reporter: Remi Bergsma
> Priority: Critical
>
> While testing a PR, I found that HA on KVM does not work properly.
> Steps to reproduce:
> - Spin up some VMs on KVM using a HA offering
> - go to KVM hypervisor and kill one of them to simulate a crash
> virsh destroy 6 (change number)
> - look how cloudstack handles this missing VM
> Result:
> - VM stays down and is not started
> Expected result:
> - VM should be started somewhere
> Cause:
> It doesn’t parse the power report property it gets from the hypervisor, so it never marks it Stopped. HA will not start, VM will stay down.
> Database reports PowerStateMissing. Starting manually works fine.
> select name,power_state,instance_name,state from vm_instance where name='test003';
> +---------+--------------------+---------------+---------+
> | name | power_state | instance_name | state |
> +---------+--------------------+---------------+---------+
> | test003 | PowerReportMissing | i-2-6-VM | Running |
> +---------+--------------------+---------------+---------+
> 1 row in set (0.00 sec)
> I also tried to crash a KVM hypervisor and then the same thing happens.
> Haven’t tested it on other hypervisors. Could anyone verify this?
