The /dev/vmbus/hv_fcopy device won't be created unless the 'Guest
Service Interface' integration service is enabled in the VM. It isn't
enabled by default. This can be checked with the following PowerShell

Get-VMIntegrationService 'Guest Service Interface'

Is it possible for you to test other kernels with that instance? It
would be good to confirm this is in fact a regression and bisect it
down.
