https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263569 Bug ID: 263569 Summary: sr-iov: ixv0 connection lost after loading vm with a passthrough device Product: Base System Version: 13.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: benoitc@enki-multimedia.eu I am trying to use SR-IOV on my machine with an IX driver, but each time i start the vm on the passthrough devices the connections which is started on= the virtuall function dedicated for the host, the connection hangs and it is not possible to setup the connection back until I reboot. Do anyone know what i= 'm missing in my configuration? I don't see any useful logs in dmesg. The card is the HP Ethernet 10Gb 2-port 560SFP+ Adapter 665249-B21 which is= an Intel X520-DAA2. Maybe related but when restarting netif I am getting this message: "Mailbox API negotiation failed in if_init" .I am using the intel-ix-kmod port. I tr= y to update it to the latest 3.3.30 version which provided the same results. I've the following configuration to setup sr-iov: ``` more /etc/iov-ix0.conf PF { device: "ix0"; num_vfs: 4; } DEFAULT { passthrough: true; allow-set-mac: true allow-promisc: true; } VF-0 { passthrough: false; mac-addr: "36:6b:d2:f9:a9:08"; } ``` and in loader.conf: ``` ifconfig_ixv0=3D"up" cloned_interfaces=3D"lo1 bgp services" vlans_ixv0=3D"bgp services" create_args_bgp=3D"vlan 1000" create_args_services=3D"vlan 2000" ifconfig_bgp_ipv6=3D"inet6 XXX/64" ``` vms starts and the device seeps to be setup: ``` ixv0@pci0:8:0:128: class=3D0x020000 rev=3D0x01 hdr=3D0x00 vendor=3D0x8086 device=3D0x10ed subvendor=3D0x103c subdevice=3D0x17d3 vendor =3D 'Intel Corporation' device =3D '82599 Ethernet Controller Virtual Function' class =3D network subclass =3D ethernet cap 11[70] =3D MSI-X supports 3 messages, enabled Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] =3D PCI-Express 0 endpoint max data 128(128) max read 128 ecap 0001[100] =3D AER 1 0 fatal 0 non-fatal 0 corrected ecap 000e[150] =3D ARI 1 ppt0@pci0:8:0:130: class=3D0x020000 rev=3D0x01 hdr=3D0x00 vendor=3D0x8086 device=3D0x10ed subvendor=3D0x103c subdevice=3D0x17d3 vendor =3D 'Intel Corporation' device =3D '82599 Ethernet Controller Virtual Function' class =3D network subclass =3D ethernet cap 11[70] =3D MSI-X supports 3 messages Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] =3D PCI-Express 0 endpoint max data 128(128) max read 128 ecap 0001[100] =3D AER 1 0 fatal 0 non-fatal 0 corrected ecap 000e[150] =3D ARI 1 ppt1@pci0:8:0:132: class=3D0x020000 rev=3D0x01 hdr=3D0x00 vendor=3D0x8086 device=3D0x10ed subvendor=3D0x103c subdevice=3D0x17d3 vendor =3D 'Intel Corporation' device =3D '82599 Ethernet Controller Virtual Function' class =3D network subclass =3D ethernet cap 11[70] =3D MSI-X supports 3 messages Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] =3D PCI-Express 0 endpoint max data 128(128) max read 128 ecap 0001[100] =3D AER 1 0 fatal 0 non-fatal 0 corrected ecap 000e[150] =3D ARI 1 ppt2@pci0:8:0:134: class=3D0x020000 rev=3D0x01 hdr=3D0x00 vendor=3D0x8086 device=3D0x10ed subvendor=3D0x103c subdevice=3D0x17d3 vendor =3D 'Intel Corporation' device =3D '82599 Ethernet Controller Virtual Function' class =3D network subclass =3D ethernet cap 11[70] =3D MSI-X supports 3 messages Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] =3D PCI-Express 0 endpoint max data 128(128) max read 128 ecap 0001[100] =3D AER 1 0 fatal 0 non-fatal 0 corrected ecap 000e[150] =3D ARI 1 ``` VM is started using vm-bhyve: ``` loader=3D"uefi-csm" cpu=3D1 memory=3D2G passthru0=3D8/0/130=3D5:0 disk0_type=3D"virtio-blk" disk0_name=3D"disk0.img" uuid=3D"ac3dafab-bedb-11ec-b24d-1402ec690a80" ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
