I've checked config files from kernel 2.6.32-707.el6: virtio-input has been introduced in 4.1 and not backported to 2.6.32, only to 3.10.0-280. Are you sure it works for x86_64? You should check you don't have an USB keyboard with "lsusb" and "lspci -v". Thanks On x86_64 guest:
# lspci -v

It seems x86 guest doesn't recognize QEMU Virtio Keyboard too, but it can use a default keyboard ("AT Translated Set 2 keyboard"), although I added "-nodefaults" to the qemu command line.
So x86_64 also have this problem.
I see that you mentioned "virtio-input is not backported to 2.6.32", so you can decide what to do next with this bug.
Thanks a lot.
I'm pretty sure we're not going to add a whole new keyboard driver to RHEL6 at this late stage, particularly when an XHCI keyboard will work perfectly well. |
Description of problem: When testing PPC RHEL6.9BE Guest, keyboard doesn't work when using virtio-keyboard-pci device Version-Release number of selected component (if applicable): Host: 3.10.0-679.el7.ppc64le qemu-kvm-rhev-2.9.0-9.el7.ppc64le SLOF-20170303-4.git66d250e.el7.noarch guest kernel: 2.6.32-696.el6.ppc64 How reproducible: 100% Steps to Reproduce: 1. Boot guest with virtio-keyboard-pci, but without usb-kbd (for POWER should add -nodefaults) qemu cli: /usr/libexec/qemu-kvm \ -name yilzhang_vm \ -m 8192 -smp 8,sockets=2,cores=2,threads=2 \ -rtc base=localtime,clock=host \ -boot menu=on \ -monitor stdio -nodefaults \ -vga virtio \ -device virtio-keyboard-pci,id=kbd0,serial=virtio-keyboard \ -vnc :1 \ \ -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x4 \ -drive file=rhel69.qcow2,format=qcow2,id=drive_sysdisk,if=none,cache=none,aio=native,werror=stop,rerror=stop \ -device scsi-hd,drive=drive_sysdisk,bus=scsi0.0,id=sysdisk,bootindex=0 \ -netdev tap,id=net0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown,vhost=on \ -device virtio-net-pci,netdev=net0,id=nic0,mac=52:54:00:c3:e7:84,bus=pci.0,addr=0x5 \ -device nec-usb-xhci,id=xhci0,bus=pci.0,addr=0x6 \ -device usb-mouse,bus=xhci0.0 -device usb-tablet,bus=xhci0.0 2. Login guest via vnc, and check if keyboard works well Actual results: Connect guest via vnc, and find that keyboard doesn't work at all. (qemu) info pci Bus 0, device 0, function 0: VGA controller: PCI device 1af4:1050 IRQ 0. BAR0: 32 bit prefetchable memory at 0x80000000 [0x807fffff].

BAR4: 64 bit prefetchable memory at 0xffffffffffffffff [0x00003ffe]. id "kbd0" Expected results: Keyboard works well Additional info: 1. x86 doesn't have this problem (guest kernel version: 2.6.32-696.el6.x86_64) 2. Just change guest kernel from RHEL6.9BE to RHEL7.4le (3.10.0-675.el7.ppc64le), keyboard will work well
