oooo, it was the hosted engine itself.

  RAM     4096

  Max RAM 0

  I don't think I've touched the system settings on the hosted engine vm itself though.

This (testlab) cluster was originally installed with 4.0 (I think) and gets constantly upgraded with the pre-releases...

Thanks for running oVirt pre-releases in your testlab! Simone, Martin, can you please follow up on this?

 

 

After a bit of faffing around to clean up leftovers of the failed upgrade, I'm now running v4.2.0 and it's certianly different :)

Great to see you managed to upgrade to 4.2.0 alpha!

 

  I did have one firefox browser that refused to load the dashboard reporting 500 errors, but that appears to have been down to cached content (on OS X).

Greg. any clue? If I understood it correctly, you've been able to access the dashboard from some browser but failed on one firefox instance right?

 

  I look forward to playing with the new UI.

 

Thanks,

Brett

Thanks Tomas,

  I'm restoring backup at the moment, I'll let you know how it goes when on the next attempt.

Hey Brett,

That is strange - it looks like you have some VM which has memory size larger than the max memory size.

You need to go over your VMs / templates to find which one has this wrong config and change it.

Alternatively, to find it faster if you have many vms/templates, you could run this SQL query against your engine database:
select vm_name from vm_static where mem_size_mb > max_memory_size_mb;

What's the minimum RAM required now ?
