[Bug 378733] [NEW] qemu monitor virtual console won't do scrollback via VNC

[Mike Hicks]

Public bug reported:

Binary package hint: qemu

In order to prevent myself from inadvertently killing virtual machines
that I run via qemu, I've been running them with VNC enabled ("-vnc" or
"-vnc :1", etc. on the qemu command line) instead of using the normal
GUI.  However, this has the drawback that I can't use Ctrl+PgUp,
Ctrl+PgDn, Ctrl+Up, or Ctrl+Down to look at the scrollback text when I'm
in the qemu monitor screen (Ctrl+Alt+2).

Because commands like "help" and "info" will show more than one
screenful of information, I am unable to see much of the text that has
scrolled by.  I would have expected this to work.  And yes, I have tried
both using the Ctrl+<key> combinations on my keyboard and using the F8
popup menu in my VNC client to set the Ctrl key as pressed.  (I'm using
xvnc4viewer as my client).

I see two ways of correcting this: either get the scrollback working via
VNC, or implement a "more" or similar command to allow the text to be
viewed a page at a time.  A syntax like "more help" would be fine, or a
pipe syntax like "help | more" would work too.

I believe this also affects the kvm package since it is based around
qemu.
