Xen devel - Jul 2007 - [PATCH] [PVFB] Fix shift key for graphical vnc display

Hi All,

There is a problem in the input of the key in the VNC connection on the PV 
domain.
When client''s keyboard is not the same as the kind of the keyboard of
PVFB
 and GuestOS, it is not possible to input it correctly.

This patch handled the state of shift from the set keymap.
When client''s keyboard is not same as the kind of PVFB/GuestOS,
it is possible to input it correctly.
It was confirmed to input it correctly mutually with this patch between en-us
and ja.
