https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D245392 Bug ID: 245392 Summary: bhyve PCI passthru built-in rtl8168 to OpenBSD no packets (AMD Ryzen 3 1200) Product: Base System Version: 12.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: me@anatoli.ws Created attachment 213114 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D213114&action= =3Dedit a dmesg from FreeBSD 12.1-RELEASE r354233 running on the machine Trying to PCI passthru a built-in NIC on 12.1-RELEASE r354233 to OpenBSD 6.6 inside bhyve on a AMD Ryzen 3 1200. OpenBSD sees the NIC (re0 Realtek 8168), it can even detect the link state correctly, but it can't send/receive packets. /boot/loader.conf contains hw.vmm.amdvi.enable=3D"1". I launch the instance this way: sudo bhyve -c 4 -m 4G -wuHP \ -s 0,amd_hostbridge \ -S \ -s 2,passthru,5/0/0 \ -s 3,virtio-blk,/vm/ppt/disk.img \ -s 5,virtio-net,tap0 \ -s 31,lpc -l com1,/dev/nmdm0A \ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \ ppt When OpenBSD runs on the machine without virtualization, the nic works correctly. When virtualized with passthru, it can't send/receive data on the nic, but it detects the link correctly. Another (possibly related) issue is if I execute the command above without = -w (same happens with or without PCI passthru), OpenBSD fails at initialization with "protection fault trap, code=3D0; Stopped at identifycpu+0xa5c: wrmsr". Please find attached the following files: * dmesg.freebsd: a dmesg from FreeBSD 12.1-RELEASE r354233 running on the machine. * dmesg.openbsd.native: a dmesg from OpenBSD 6.6 running on the maching without virtualization. * dmesg.openbsd.bhyve: a dmesg from OpenBSD 6.6 running inside bhyve, lauc= hed from the FreeBSD (the first dmesg) with the command mentioned above. * pcidump.native: a result of the pcidump command under OpenBSD 6.6 runnin= g on the machine without virtualization (5:0:0 is the device in question). * pcidump.bhyve: a result of the pcidump command under OpenBSD 6.6 inside bhyve (0:2:0). * vm-bhyve.passthru: a result of the vm-bhyve passthru command right before launching an OpenBSD bhyve instance. * boot.crash: the OpenBSD boot sequence that leads to a crash when bhyve is invoked without the -w option. --=20 You are receiving this mail because: You are the assignee for the bug.=
