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 ^]

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.
