Xen devel - Oct 2005 - [PATCH]Cannot send special keys, such as Ctrl+Alt+Del

Here is the patch useful to send special keys that your graphical user
interface intercepts at low level, such as ctrl-alt-del in X Window.

This patch adds a command "sendkey" to deal with it in the monitor,
you
can send keys to the vm. Use - to press several keys simultaneously.
Example: 
sendkey ctrl-alt-f1

Is this generally useful? If you are proposing this as a general way to 
get around useful key sequences getting stolen by the local gui, it 
doesn''t seem the kind of interface that users will want. Can we remap 
such key sequences in some way to make them accessible to users without 
needing to run a monitor program and type in sequences longhand?

vmware/vncviewer use a menu such as "Send ctrl-alt-del" to do the same
thing, but it''s limited for our environment because various key
sequences
are stolen by linux host.
this patch is borrowed from qemu and good enough at this point (we
didn''t
use this frequently)

Keir, we did consider such way to supply useful key sequences. But if we
remap such key sequences, it is very possible to conflict with other
applications and meanwhile users have to change their habits and
remember the mappings. Then maybe they''ll get some confused. Until now,
you know, there isn''t standard way to deal with combined keys in
virtual
machines, such as vmware, qemu, and so on.
So this way is the easiest remembered, least conflicted one, I think.

Thanks!
