Description Jason 2018-07-24 23:37:00 UTC

Description of problem:

Site had their environment setup on 4.1.10 with some clusters on 4.0 and 4.1 mode. They then upgraded straight to 4.2 without upgrading the clusters or the RHV-M/Hosts to the latest minor release.

Once upgraded they noted that all users 1300'ish could see all VMs. They also noted that shortly (usually within 5 seconds) of a user logging in and seeing all the VMs the screen will "Flicker" and go blank (white) and nothing is visible. 

Site confirmed they are on the latest 1.3 version of the ovirt-web-ui.

How reproducible:

Everytime on this site.


Actual results:

see above

Expected results:

Users should only see the VMs assigned/created by them and the scree should not go blank.

Additional info:

This is an Extremely urgent with this site and may possibly be causing others issues.

Will attach logs shortly as well as details about the site/case.

But you say they have 1.3.9, so they do have the latest release ovirt-web-ui. 
ui.log is not relevant for VM portal, only for webadmin. Can you get a javascript console log from the browser?

Hi Michal,

They have downgraded to 4.1 as they reached their deadline. 
I don't think anything was captured on the browser side. Greg or Travis are probably more aware than me, but I don't think additional data can be requested (and its all secure anyway, its hard to get any logs).

Comment 19 Germano Veit Michel 2018-07-26 04:57:15 UTC

How reproducible:
50% - Just the "See All VMs" part.
    - As discussed with Greg, the crash might be due to the huge amount of VMs they see.

Steps to Reproduce:
1. Install RHV 4.1.10
2. Create a Pool with 5 VMs
3. Add 2 AD users
4. Assign UserRole for both Users
5. Login with each user to User Portal, Grab a VM
6. Upgrade to 4.2
7. Login to VM Portal with one of the 2 AD users
   RESULT: user is able to see all 5 VMs, see screenshot
8. Update ovirt-web-ui to 1.3.9 (because this is left behind currently)
   RESULT: same thing, all 5 VMs of the pool can be seen

NOTE: user can also manipulate all VMs, including shutting down VMs from other users and get as many VMs as he wants.

Comment 22 Michal Skrivanek 2018-07-26 06:37:09 UTC

both users have UserRole set on System therefore they can see the same set of VMs - all of them

Right, I configured both users with UserRole in RHV 4.1. When logging to the User Portal each could only see the Pool (not any VM), then get a VM from the Pool. At this point they would only see their VM.

After upgrading to 4.2, they don't see the "Pool" to request a VM from, but see all VMs of the Pool.

Is this really a permission problem? Is it the new portal? I'm very confused.

Comment 42 Greg Sheremeta 2018-08-24 19:17:34 UTC

Use this BZ 1608093 for the white screen.
Use BZ 1609147 for the pool permission issue.

Comment 43 Greg Sheremeta 2018-10-11 15:46:45 UTC

ovirt-web-ui 1.4.4 (ovirt 4.2.7) has a proper error screen instead of white screen of death. When an error is encountered, a helpful stack trace should print in the browser console.

Comment 47 Lucie Leistnerova 2019-02-25 16:33:35 UTC

Upgrade engine 4.1.11 -> 4.2.8 -> 4.3 (directly to 4.3 is not supported) was OK and user sees only his running VMs from the pool in VM portal. No blank page.
User was in group that had UserRole on the pool.

verified in ovirt-web-ui-1.5.0-1.el7ev.noarch with ovirt-engine-4.3.0.4-0.1.el7.noarch

Feel free to reopen, when the problem persist.
