https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229990 Bug ID: 229990 Summary: FreeBSD 11.2 on Hyper-V: hn0: network changed, change 1 Product: Base System Version: 11.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: bazald@gmail.com I am attempting to run FreeBSD 11.2 under Hyper-V on Windows 10 1803. I have tried both Gen 1 and Gen 2 virtual machines, as well as both legacy and non-legacy network adapters under Gen 1, and networking seems to be difficu= lt to get right, at least with Wi-Fi. The only configuration that seems to work at all is using a Gen 2 VM (non-legacy network adapter). I initially attempted to use a virtual switch configured to access the external network, with sharing allowed, and I quic= kly got MAC collision errors. I'm uncertain as to whether that's the expected result. Moving on to the default switch, sharing my Wi-Fi with that, I seem to have working Internet access. I added "net.link.ether.inet.max_age=3D60" to /etc/sysctl.conf, which seems to be important for maintaining the connectio= n. As a new FreeBSD user, it is distressing that https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/best= -practices-for-running-freebsd-on-hyper-v fails to document that it truly ought to be added to /etc/sysctl.conf. Finally, even with this apparently working connection, we get to the bug I'm actually here to report. I'm still getting flooded with "hn0: network chang= ed, change 1" messages on the terminal. The patch at https://reviews.freebsd.org/D8295 seems to be to blame? I believe NDIS_NETCHANGE_TYPE_POSSIBLE is being reported to the console, and perhaps correctly so given the networking issues with Hyper-V, but some method to at least suppress the messages would be most welcome. --=20 You are receiving this mail because: You are the assignee for the bug.=
