Hi All, Is anyone using PCI passthru of network adapters with OpenBSD 6.6 inside bhyve?
I tried different combinations: * Host: FreeBSD 12.1R and 13C * CPUs: Intel i7 7600U, 8550U, AMD Opteron 6300 and Ryzen 1200 * NICs: Intel PRO/1000 (onboard) & RTL8111/8168/8411 (onboard and PCIe slot) The behavior is always the same: OpenBSD guest sees the adapters and in most of cases even correctly senses the media state, but it can't send/receive packets. Though once I've seen with tcpdump on another machine directly connected to the host an ARP request packet coming from the OpenBSD guest, the other machine send a corresponding ARP reply, but then nothing. So probably only the incoming traffic is not working. I'm investigating it with FreeBSD devs (here is a bug report with dmesgs and all other relevant info: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245392), it looks like something related to MSI interrupts, but I'd like to confirm if anyone has a working setup of bhyve nic pci passthru with OpenBSD as a guest. Thanks, Anatoli
