Hyper-V Requirements:      A hypervisor has been detected. Features required for Hyper-V will not be displayed.

Steps to reproduce

1. crc setup
2. crc start HyperV default interface only picked up IPv6 address and not IPv4
3. crc stop
4. Change default switch to external switch in HyperV HyperV external interface picked up both IPv4 and IPv6 address ssh failed - missing file from machine
5. crc stop
6. Copied .crc\cache\crc_hyperv_4.2.0-0.nightly-2019-09-26-192831\id_rsa_crc to .crc\machines\crc\id_rsa
7. crc start cannot update nameserver
8. crc stop
9. crc start -n “8.8.8.8” failed again
