Currently I'm trying to setup a Foreman 1.10 install on Redhat 6 against a vSphere 4.1 installation.

The compute resource was created without any issues.
However when I try and create a new host, I get an error:

Unable to save
Failed to create a compute ACTINT-VMware (VMWare) instance git.card.co.uk: InvalidProperty: 

The issue happens post vm creation and I can see VM created , on the vcenter but with right number of CPU's and 32 MB ram (wrong) and no controllers etc

the only devices there are memory,cpu , video card and vmci device ..

Full log as below...
