Description Simone Tiraboschi 2017-11-29 17:28:28 UTC
Description of problem:
https://gerrit.ovirt.org/#/c/84802/ changed the OVF structure replacing 'http://schemas.dmtf.org/ovf/envelope/1/' with 'http://schemas.dmtf.org/ovf/envelope/1'

and now ovirt-ha-agent fails with:

Version-Release number of selected component (if applicable):
ovirt-hosted-engine-ha.noarch          2.2.0-0.0.master.20171113160114.20171113160111.git3819ce6.el7.centos

How reproducible:
100%

Steps to Reproduce:
1. deploy hosted-engine and upgrade the engine to latest rpms
2. wait for OVF_STORE creation
3. check the status of ovirt-ha-agent

Actual results:
[root@c74h3 ~]# systemctl status ovirt-ha-agent
● ovirt-ha-agent.service - oVirt Hosted Engine High Availability Monitoring Agent
   Loaded: loaded (/usr/lib/systemd/system/ovirt-ha-agent.service; enabled; vendor preset: disabled)
   Active: activating (auto-restart) (Result: exit-code) since mer 2017-11-29 18:25:46 CET; 7s ago
  Process: 24857 ExecStart=/usr/share/ovirt-hosted-engine-ha/ovirt-ha-agent (code=exited, status=157)
 Main PID: 24857 (code=exited, status=157)

nov 29 18:25:46 c74h3.localdomain systemd[1]: ovirt-ha-agent.service failed.

KeyError: '{http://schemas.dmtf.org/ovf/envelope/1/}id' in /var/log/ovirt-hosted-engine-ha/agent.log



Expected results:
ovirt-ha-agent is up and running correctly parsing the OVF_STORE

Additional info:
https://gerrit.ovirt.org/#/c/84802/ introduced the correct URL, ovirt-ha-agent should be able to correctly handle it but, at the same time, it should be also backward compatible with OVF_STORE created by previous engine releases.

Comment 1 Red Hat Bugzilla Rules Engine 2017-11-29 17:30:40 UTC

Comment 3 Nikolai Sednev 2017-12-13 09:30:17 UTC
Using ovirt-engine-appliance-4.2-20171210.1.el7.centos.noarch and ovirt-hosted-engine-setup-2.2.1-0.0.master.20171206172737.gitd3001c8.el7.centos.noarch during and after deployment of SHE on pair of hosts, over Gluster, and after adding some NFS data storage domain, I did not reproduced the original issue, hence moving to verified.

I'm still seeing this with ha-2.2.3-0.0-master.20171218181916.20171218181911.git4c22b93.el7 - on Ansible based deployment (in OST). Will now check with vintage deployment.

Also in vintage deployment. I'll open a separate bug.
