https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236922 --- Comment #19 from Tommy P <tommyhp2@gmail.com> --- More specific VM's configuration: PCI-E bus: -device virtio-serial-pci,id=virtio-serial0,bus=pci.1,addr=0x0 PCI bus: -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 Note the bus=pci.1 vs bus=pci.0. If I'm correct, the pci.1 (PCI_ABI_VERSION) configure that device is connected to the PCI-E bus instead PCI (pci.0), which utilize different ID as per /usr/src/sys/dev/virtio/pci/virtio_pci.h: /* VirtIO PCI vendor/device ID. */ #define VIRTIO_PCI_VENDORID 0x1AF4 #define VIRTIO_PCI_DEVICEID_MIN 0x1000 #define VIRTIO_PCI_DEVICEID_MAX 0x103F /* VirtIO ABI version, this must match exactly. */ #define VIRTIO_PCI_ABI_VERSION 0 -- You are receiving this mail because: You are the assignee for the bug.help
