Ran into this particular issue while reinstalling a Hyper-V host and then adding back to SCVMM. I noticed the reinstalled host was not showing as an available target when trying to create a new VM. You can see the three errors it popped up in the wizard when the reinstalled host was selected. Turns out, I had forgotten to associate the logical networks with the teamed adapters after reinstalling the host. To fix this, do the following

1. Open the properties of the physical host in SCVMM
2. Select the Hardware tab and scroll down to the Network Adapters section. Select the team or physical adapter that supports the VMNetwork to be assigned to VMs. In the screenshot below you can see its unchecked which was causing the error. 
3. Go back to SCVMM and now the issue should be corrected.

Hope that helps!
