I've found this can be resolved when /dev/input/ is mounted read/write
on the guest. In order to make it accessible also to non-root users,
/dev/input/ must be set world writable on the host (this is not very
good, but I couldn't find any better way to make it work).

    MZ> Or mythtv refuses to play TV and reports errors like this:

    MZ> VideoOutputXv Error: Failed to allocate X shared memory.

This error still persists, together with error messages like

  BadAccess (attempt to access private resource denied)
  ...
  X Error: BadShmSeg (invalid shared segment parameter) 170
