[Qemu-devel] [Bug 1738283] Re: 'Less than' (<), 'more than' (>), and 'pipe' (|) can't be typed via VNC

[Daniel Berrange]

By default virt-manager will *not* enable the '-k en-us' argument,
because that forces use of a specific keyboard layout in QEMU's VNC
server. For that to work, the VNC client keymap must exactly match the
QEMU VNC server keymap, and must also exactly match the guest OS keymap.

Instead virt-manager leaves off the "-k en-us" argument, which will
cause the VNC servers raw scancode extension to be activated with
compatible clients. Virt-manager uses GTK-VNC which activates this
extension, and so passes raw XT scancodes from virt-manager to QEMU to
the guest OS, which generally makes everything "just work"

IOW, if virt-manager works correctly, but tigerVNC does not work
correctly, this probably means that tigervnc is not activating the raw
scancode extension.

Title:
  'Less than' (<), 'more than' (>), and 'pipe' (|) can't be typed via
  VNC

Status in QEMU:
  New

Bug description:
  If I start QEMU 2.11 (from
  https://build.opensuse.org/package/show/Virtualization/qemu) VM with
  VNC, I am unable to type following three characters: 'less than' (<),
  'more than' (>), and 'pipe' (|) on en_US QWERTY keyboard. Other
  characters work fine. QEMu version 2.10.1 worked fine.

  /usr/bin/qemu-kvm -m 2048 -cpu kvm64 -drive
  media=cdrom,if=none,id=cd0,format=raw,file=OI-hipster-
  minimal-20171031.iso -device ide-cd,drive=cd0 -boot once=d,menu=on
  ,splash-time=5000 -device usb-ehci -device usb-tablet -smp 1 -enable-
  kvm -vnc :91,share=force-shared

  The ISO can be downloaded here: https://www.openindiana.org/download/

  Also tried Fedora-Server-dvd-x86_64-25-1.3.iso and it's the same
  situation.

  If I run the same command without '-vnc :91,share=force-shared',
  everything works just fine.
