Latest version of oVirt node 4.2 installed on three hosts.  I completed successfully the cockpit gdeploy process to deploy HCI.  All of that went well with no errors.  I then proceeded to the hosted engine deployment step which eventually failed (log attached). 

This is the current status:

--== Host 1 status ==--

conf_on_shared_storage             : True

If I do hosted-engine --console I get:

The engine VM is running on this host

Connected to domain HostedEngine

Escape character is ^]

error: internal error: cannot find character device <null>

does anyone know why it may have failed or what I could do to recover from this?  I'm thinking it could have potentially failed due to some problem with network config.  If I could get a console in to the engine VM I might be able to fix it but that serial error above is preventing me from reaching the vm console to diagnose further. 

Log of deploy attached:

Thanks!
