FWIW, the big sur betas have been a lot less stable than usual, especially this late in the game. Apple's continuing to make substantial changes to the underlying OS plumbing, so it wouldn't be a surprise if they borked something again.
Hi howaldoliver ,
The problem is, when I choose "Autodetect" or "Wi-Fi" as Network setting in vm preferences, I can't do various internet-base operations anymore in the vms.
Does this problem if using NAT for VM?
