Create host - Interfaces throws a "Error loading interfaces information: Internal Server Error" about foreman_hyperv

The issue is due to the compute resource cache, which is why I've not exposed the ability to enable said cache when creating the a Hyper-V provider instance.
The ruby marshaller isn't able to dump the fog-hyperv models because of a singleton somewhere inside of them.

If the cache has become enabled anyway - despite there being no option for it, then you might need to drop into the rails console (foreman-rake console) and run the following,

ComputeResource.where(type: 'ForemanHyperv::Hyperv').each { |cr| cr.caching_enabled = false; cr.save }

Thanks, that solved the problem. The problem started after a upgrade from 16.1 to 17.1

I guess it could be that it automatically enabled caching on all compute resources when upgrading, might have to look into explicitly disabling the cache until I've gotten marshalling working in the fog provider.
