Hi,

I followed deployment manual from [1] and configured two DCs with
single cluster each.
During configuration of the UI I noticed that in optimizer result tab there was:

Status: Data refresh failed: undefined

with Martin's help we found that when setting

security.mixed_content.block_active_content

to false in FF configuration it works and I can see:

Status: Solution received

During the installation of second host network configuration failed
and I opened BZ [2].
When I restored network configuration to the host I wanted to
provision vms to see optaplanner
suggestions but my rhel6 failed to start any vms due to:

Vdsm is not able to start any vms but engine still thinks that host is 'UP'.

Thanks,
