I have been deploying VMWare images from a template for weeks on Katello / Foreman 16.2. Today I updated the OS and now every time I try to deploy a new VM it fails with undefined method `raw_networks' for #<Fog::Compute::Vsphere::Real:0x0000000fd65a60>. My setup is part of a POC and doesn't deploy from anything but an image, but the failure is happening immediately after VMWare has copied the template and told Foreman that the process has completed step 1.

I do see that tfm-rubygem-fog-vsphere-2.3.0-1.el7.noarch was updated as part of the yum update today.

When I downgraded to the previous tfm-rubygem-fog-vsphere.noarch 0:2.1.1-2.el7.noarch, I no longer had the issue.

It appears that tfm-rubygem-fog-vsphere-2.3.0-1.el7.noarch has some issue communicating with VMWare that wasn't present in the older version.
