They all look like the same bug in 3 different places. Please open a bug at https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt-engine
and include your reproducer steps and your logs. Please set the "ovirt team" to UX. Thanks!

I managed to fix the error with HA broker and agent continually crashing.  I found that it was not a permissions problem on the path mentioned in the log:

/var/run/vdsm/storage/248f46f0-d793-4581-9810-c9d965e2f286/14a20941-1b84-4b82-be8f-ace38d7c037a/8582bdfc-ef54-47af-9f1e-f5b7ec1f1cf8

but this folder had wrong permissions:

_exports_hosted__engine/248f46f0-d793-4581-9810-c9d965e2f286/images/19f114a1-e1c3-41c5-9fcb-b6099612d012

That seems to have resolved the agent and broker problem.  The UI error when clicking network interfaces or snapshots for hosted engine VM still appears to exist.  Here is the ui log from that:

Network interfaces tab for hosted engine VM:

Right. ui.log will include the same stack trace that it gives in the browser -- just deobfuscated (automatically now).

So, yes, please share it.
