Please update the qemu-kvm-rhev and seabios versions. Thanks.
Hi aliang, i think you should confirm if there exist one rom for this device. path: /sys/bus/pci/devices/$DEVICE/ Without rom file, it is normal. Agree with comment 3, unless the device has a *bootable* ROM this is the expected behavior. SR-IOV VFs do not have a ROM by definition so the expected results are wrong for this device. Only the PF even has a chance of being bootable without specifying a romfile for the device. If host dmesg reports an invalid rom file message then the rom is not bootable. Check result: This is a configuration issue, not a product bug. XL710 nic need to be configured in "Device Setting" in BIOS. "Device Setting" ---> XL710 nic --->"NIC Configuration" ---> "Legacy Boot Protocol" ---> "PXE" By default, the legacy boot protocol is "NONE", so we can not see the PF in seabios even if the device has one bootable rom. Configured as yanan suggested, PF device can be displayed on seabios boot menu, see attachment. ****************Cmds to start guest*********** /usr/libexec/qemu-kvm -name rhel7 \ -machine pc,accel=kvm,usb=off,vmport=off \ -cpu host \ -m 4096 \ -realtime mlock=off \ -smp 8 \ -uuid 1534fa42-4818-4493-9f67-eee5ba758385 \ -no-user-config -nodefaults \ -chardev socket,id=qmp_id_catch_monitor,path=/var/tmp/test1,server,nowait \ -mon chardev=qmp_id_catch_monitor,id=monitor,mode=readline \ -no-hpet \ -boot menu=on,splash-time=6000 \ -vga qxl \ -vnc 0:3 \ -netdev tap,id=hostnet10 \ -device virtio-net-pci,netdev=hostnet10,id=net10,mac=50:54:00:49:b2:5f \ -spice ipv4,port=5000,disable-ticketing \ -enable-kvm \ -monitor stdio \ -chardev socket,id=ovmf_log,path=/var/tmp/seabios,server,nowait \ -device isa-debugcon,chardev=ovmf_log,iobase=0x402 \ -drive file=/home/rhel6_8.qcow2,if=none,id=drive-ide0-0-0-0,format=qcow2,cache=none,aio=native,snapshot=off \ -device ide-hd,bus=ide.0,drive=drive-ide0-0-0-0,id=ide0-0-0-0 \ -device vfio-pci,host=04:00.0,id=hostnet_PF \ ********************************* When i create ipxe rom for VF device, it seemed not be supported.
