Description John Pierce 2015-03-16 13:20:52 UTC 
Description of problem:

The latest version upstream of noVNC is 0.5.1.  The current version in OSP, 0.4, is quite old at this point, and lacks several important bug fixes.

Additionally, as of 15-Mar-2015, the official CentOS 7 update repositories are pushing novnc.noarch 0.5.1-2.el7 update out to CentOS 7 servers. So after I ran a "yum update" on my oVirt self-hosted engine running CentOS 7 yesterday (on 15-Mar), I got errors when trying to launch the noVNC console for any of VMs.

Specifically, I received a JavaScript error popup in my web browser stating: "ReferenceError: WebUtil is not defined" and in FireBug, I noticed that I was getting a 404 error regarding a missing vnc.js include file from my ovirt engine. Indeed vnc.js was missing from the path: /usr/share/novnc/include/ on my ovirt engine and that's when I discovered the yum update of noVNC occurred and the new 0.5.1 package does not have a vnc.js file anymore.

Version-Release number of selected component (if applicable):
novnc.noarch 0.5.1-2.el7 on CentOS/RHEL 7

How reproducible:
Always as of 15-Mar-2015 when the upstream CentOS yum update repositories starting pushing noVNC 0.5.1.

Steps to Reproduce:
1. Do a yum update to your CentOS 7.0 oVirt engine which should pull down the latest novnc 0.5.1 package.
2. Try to open a noVNC console to any VM running on your oVirt engine.
3. Observe JavaScript error as no console shows up.

Actual results:
JavaScript popup error stating ReferenceError: WebUtil is not defined.

Expected results:
noVNC console should render.

Additional info:
For now, I downloaded novnc-0.4-7.el7.noarch rpm and downgraded to the version that works with this command: rpm -Uvh --oldpackage novnc-0.4-7.el7.noarch.rpm.

This workaround seems necessary until oVirt webadmin code is updated to accomodate noVNC 0.5.1.
Comment 1 Sandro Bonazzola 2015-05-14 15:47:28 UTC 
Michal, noVNC is causing a (minor?) regression here, I suggest to re-target this to 3.5.4.
Comment 2 Michal Skrivanek 2015-05-14 16:01:54 UTC 
Might be easier to push Conflicts: then
Fix won't happen any time soon, well, at least couple of weeks
Comment 3 Nicolas Ecarnot 2015-06-09 14:14:07 UTC
