Description of problem:
Provisioning VM from a template doesn't work for RHV 4.3

Version-Release number of selected component (if applicable):
RHV 4.3.0-0.8.rc2.el7

How reproducible:

Steps to Reproduce:
1. Add RHV provider
2. Go to VMs
3. Lifecycle -> Provision VMs
4. Select a template, click Continue

Actual results:
Unexpected error encountered
undefined method `uid_ems' for nil:NilClass [miq_request/prov_edit]

Expected results:
Provisioning dialog is opened

Additional info:
When provisioning the VM from the same template directly in RHV, it works. Afterwards, I'm able to see this VM in CFME.
Also, when selecting the template, CFME shows incorrect info (it shows CPUs 0, Memory 0 for this template).

There are some refresh errors, see the attached logs.

This reproduces also to me on development setup. The cluster-id is no longer saved for VMs or templates during the refresh.

Comment 7 Adam Grare 2019-02-26 15:23:13 UTC
It looks like the format of the cluster href is different than what we see from the vm:



Comment 8 Adam Grare 2019-02-26 15:29:56 UTC

^ Fixes the exception but doesn't fix the fact that the VMs don't have an ems_cluster due to the format of the ID changing.

Comment 10 Ilanit Stein 2019-02-27 11:35:13 UTC
I checked several RHV-4.3 (with & without OVN), that are not Hosted Engine - and these DO NOT have the refresh failure.
Seems the problem is specific to RHV-4.3 Hosted-Engine configuration.

Comment 11 Adam Grare 2019-02-28 16:44:34 UTC
Okay I updated https://github.com/ManageIQ/manageiq-providers-ovirt/pull/343 to reference clusters by id instead of href from vms and hosts.

Comment 12 Ilanit Stein 2019-03-04 08:52:02 UTC
We have a fix for this already on RHV side:

oliel explains on the change in cluster href seen in RHV-4.3, compared to RHV-4.2, 
and the RHV fix he added, in order to return it back to as it was in RHV-4.2:

Get all clusters under root: 

Get one specific cluster under root: 

Get all clusters under datacenters:

Those all return the cluster with an href directing to the cluster under the api root:  <cluster href=".../api/clusters/xxx>

However this one: 

Get one specific cluster under datacenters:

Returns the cluster with an href directing to the cluster under the datacenter:  <cluster href=".../api/datacenters/yyy/clusters/xxx>

I've posted a (RHV) patch making this last one direct to the cluster under the API root as well:

Comment 14 Ilanit Stein 2019-03-04 14:15:32 UTC
changed bug component to RHV as this issue is caused by a change done on RHV-4.3

Comment 22 Angelina Vasileva 2019-03-07 09:31:02 UTC
Fixed and verified for
RHV 4.3.2-0.1.el7

Comment 23 Ilanit Stein 2019-03-25 21:16:12 UTC
Moving bug to assigned since for Hosted Engine RHV-4.3.2, cluster href is still from shape:
and this fails the RHV refresh in CFME.

Comment 25 Ilanit Stein 2019-03-26 14:33:23 UTC
Ondra's fix verified:

I installed the ovirt-engine-restapi rpm built with Ondra's fix, on my engine.
and now Links under /api/clusters:
no longer have such path:  /ovirt-engine/api/datacenters/<id>/clusters/<id>
but rather: /ovirt-engine/api/clusters/<id>
as it was on RHV-4.2.
For all the clusters in my RHV-4.3.

Comment 27 Angelina Vasileva 2019-04-18 11:20:16 UTC
Moving to verified as is works for my HE as well as for Ilanit's.
