All issues appeared to be fixed in 12-STABLE now, so 12.2 should be good to go. Can you test 12-STABLE snapshot if possible? The issue wasn't necessarily around bhyve, but more iflib. Interestingly, I have exactly the same problem also with CentOS 8 + > KVM/QEMU. > > ^^^ This is interesting, maybe it isn't bhyve or a FreeBSD issue at play here if you are also getting it under KVM. We have a high count of Windows 2019 Server bhyve guests in our environment, but they are running on 11.4 and no IPv6 so I'm not going to be much use in being able to reproduce this. I'll work on getting IPv6 working on my home connection and drag a W2k19 image home, but this will take a while as I have other pressing work commitments. Please keep the list updated. Thanks Jason.
