RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Liushihui 2016-05-20 02:26:15 UTC

Description of problem:
Virt-who can't get correct rhevm4.0 api url result in virt-who can't get h/g mapping info when monitor rhevm4.0

Version-Release number of selected component (if applicable):
rhevm-4.0.0-0.6.master.el7ev.noarch
Satellite-6.2.0-RHEL-7-20160518
virt-who-0.17-1.el7.noarch
subscription-manager-1.17.6-1.el7.x86_64
python-rhsm-1.17.2-1.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1.Register system to satellite6.2
2.Make virt-who monitor rhevm4.0:
[root@hp-dl2x170g6-01 virt-who.d]# cat /etc/virt-who.d/virt 
[test-rhevm1]
type=rhevm
server=https://hp-z220-13.qe.lab.eng.nay.redhat.com:443/ovirt-engine/
username=admin@internal
password=redhat
owner=ACME_Corporation
env=Library
3. Restart virt-who and check virt-who's log
2016-05-19 21:59:48,396 [virtwho.test-rhevm1 DEBUG] RhevM-1(31984):MainThread @virt.py:run:364 - Virt backend 'test-rhevm1' started

<html><head>
<title>404 Not Found</title>

<h1>Not Found</h1>
<p>The requested URL /api/clusters was not found on this server.</p>
</body></html>

2016-05-19 21:59:49,720 [virtwho.test-rhevm1 ERROR] RhevM-1(31984):MainThread @virt.py:run:374 - Virt backend 'test-rhevm1' fails with error: Invalid XML file returned from RHEV-M: syntax error: line 1, column 49

Actual results:
RHEVM3.5's api is https://[rhevmip:443/api/
RHEVM3.5's api is https://[rhevmip:443/ovirt-engine/api/
As rhevm's api's url has been modified , it failed to get h/g mapping info.

Expected results:
Virt-who should connect correct api and get host/guest mapping info successfully.

Additional info:
Analysis virt-who's source code. After run in rhevm.py, line71

        self.clusters_url = urlparse.urljoin(self.url, "/api/clusters")

It will omit "ovirt-engine" then get wrong clusters_url="https://[rhevmip]:443/api/clusters"

Comment 1 Radek Novacek 2016-05-26 08:39:33 UTC

Fixed upstream:

https://github.com/virt-who/virt-who/commit/ae6f0020b4dddd671a31326bcae499b19f5c44b6

Comment 2 Radek Novacek 2016-05-31 08:53:47 UTC

Fixed in virt-who-0.17-2.el7.

Comment 4 Liushihui 2016-06-03 03:17:11 UTC

Verified it on virt-who-0.17-2.el7.noarch since virt-who can get host/guest mapping info when monitor rhevm4.0. Therefore, verify it.

Verified version:
subscription-manager-1.17.6-1.el7.x86_64
python-rhsm-1.17.2-1.el7.x86_64
python-rhsm-1.17.2-1.el7.x86_64

Verified process:
1.Register system to satellite6.2
2.Make virt-who monitor rhevm4.0:
[root@hp-dl2x170g6-01 virt-who.d]# cat /etc/virt-who.d/virt 
[test-rhevm1]
type=rhevm
server=https://hp-z220-13.qe.lab.eng.nay.redhat.com:443/ovirt-engine/

password=redhat
owner=ACME_Corporation
env=Library
3. Restart virt-who and check virt-who's log

    ],
