Xen devel - Sep 2006 - [RFC][PATCH] auto-starting viewer for virtual frame buffer

It seems that discussion of the virtual frame buffer has died down; I assume
this is being held off until after 3.0.3 splits...

Nevertheless, I was playing with it and wanted to put this patch out for
discussion.  This patch is a rough attempt to make the SDL/VNC viewers behave
similarly for both paravirtual and fully virtual domains.  For example, if you
specify "sdl=1" in a paravirtual config file, "xm create"
will cause sdlfb to start automatically.

My desire is to make para vs. full not appear so different to the casual user. 
Config file syntax should be similar, viewers should start in similar ways, etc.

If others agree, then there''s certainly more to do.  (Killing the VM
should close the viewer and vice versa; the vncviewer setting is not yet hooked
up; viewer paths are hard coded; etc...)  But I wanted to put the idea out there
to see if others agree with this direction.

Thanks,
Charles

I sent a new set of patches about a week ago.  There was then a rundown
of some concerns and Markus has gone through and fixed up most of those.
I''ll hopefully be posting an updated series with the patches later
today
-- just a matter of integrating the fixes, splitting out patches, etc.

Agree 100% -- my last set of patches mostly implemented everything
needed here.  I think the only thing that''s not being done similar
between PV and FV with them is vncviewer.  Which should be pretty
trivial, it''s just not one that I regularly use so I haven''t
gotten the
itch.
