Hi all,

After upgrading to 3.6.4 I'm seeing errors in the webadmin portal when
doing the following:

- Click on hosts.
- Select a host
- Put it in to maintenance
- VMs get migrated from the host
- Select an other host and go back to the first host
- I get the following messages in the screen:

I have the following version of the packages:

ovirt-engine-3.6.4.1-1.el7.centos.noarch
ovirt-engine-webadmin-portal-3.6.4.1-1.el7.centos.noarch

And it is running on CentOS 7.

Is this a bug? or went something wrong when upgrading?

It is most likely a bug in the UI. The stack trace in the UI.log is an
obfuscated stack trace so no that useful. If you can reproduce this reliably
can you do the following?

1. Install the ovirt UI debug symbol maps by running:
yum install ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-
debuginfo

This will install the symbol maps that will allow us to translate the
obfuscated code back into the original source code. We don't normally install
this by default as its rather large ~80 megabytes.

2. Log into the webadmin again and do the same steps that generate the
exception popup. Look in the UI.log again. This time the stack trace should be
readable. Please open a bug in bugzilla and include the non obfuscated stack
trace, or post the stack trace here and I can open it for you.

Thanks,
Alexander
