I can run FreeBSD under Hyper-V only using the legacy network adapter. Alas, this is de(4) which is slated for removal soon. So the problem is becoming = more pressing. Is there anyone running FreeBSD successfully under Hyper-V on Windows 10 Pr= o? If yes, are there any special settings needed? Here is a kgdb session of the crash dump written from ddb. Note that if_de = was not loaded when the crash occurred, I guess it is only read by kgdb because= I changed /boot/loader.conf back to using it.
