[Bug 579596] [NEW] VNC console doesn't accept keyboard input during PXE boot
Public bug reported: Binary package hint: qemu-kvm On lucid, I'm PXE booting a VM. Keyboard input on the VNC console works fine until PXELinux loads, so I can answer N to: Boot from (N)etwork or (Q)uit? N just fine, but once PXELinux loads, the VNC console ignores all keyboard input at the boot: prompt. No matter what keystrokes I hit, nothing happens on the VNC console. Input on PXELinux's *serial* console works fine. I can boot a target and keyboard input on the VNC console works fine when the target boots. What I type on the PXELinux serial console appears in the PXELinux VNC console. Interestingly, if I request a nonexistent boot target on the serial console, the VNC console starts accepting keyboard input. For example: r...@pxe-244:~# virsh console foo Connected to domain foo Escape character is ^] PXELINUX 3.63 Debian-2008-07-15 Copyright (C) 1994-2008 H. Peter Anvin boot: a Could not find kernel image: a boot: The VNC console now accepts keyboard input. I have kvm-pxe installed (obviously, since the VM *does* successfully load PXELinux). I'm not sure how to troubleshoot this further, or even if this is a bug in qemu-kvm proper; this is a strange failure mode. The libvirt domain XML for the VM I'm booting is below. It was created by a local tool, but using virt-manager(1) to create and PXE boot a VM exhibits the same behavior. domain type='kvm' namefoo/name uuidc80f27f4-cf2d-2125-9dd5-ca35855bdf42/uuid memory2097152/memory currentMemory2097152/currentMemory vcpu1/vcpu os type arch='x86_64' machine='pc-0.12'hvm/type boot dev='network'/ /os features acpi/ /features clock offset='utc'/ on_poweroffdestroy/on_poweroff on_rebootrestart/on_reboot on_crashrestart/on_crash devices emulator/usr/bin/kvm/emulator disk type='file' device='disk' source file='/var/lib/libvirt/images/foo.raw'/ target dev='vda' bus='virtio'/ /disk interface type='bridge' mac address='02:00:00:3d:7c:a5'/ source bridge='br0'/ target dev='vnet0'/ model type='virtio'/ /interface serial type='pty' target port='0'/ /serial console type='pty' target port='0'/ /console input type='mouse' bus='ps2'/ graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'/ video model type='cirrus' vram='9216' heads='1'/ /video /devices /domain ** Affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New -- VNC console doesn't accept keyboard input during PXE boot https://bugs.launchpad.net/bugs/579596 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
