[Xen-users] SDL display of HVMs -- how?

I''m having some trouble working out how to make the SDL interface
for HVM domUs appear. The documentation simply says "it will appear"
when you start the domU, but doesn''t state what packages or libraries
are needed in order for this magic to happen, or explain how to debug
it if it doesn''t happen. All that I''m getting at the moment is
a domU
(running WinXP -- I installed with the VNC interface) starting up, and
no way of interacting with it.

   I''m using Xen from hg of last week, and Debian testing as the Dom0.

   Is there some documentation that I''ve missed, or could anyone shed
some light on this issue for me?

   Thanks,
   Hugo.

Re: [Xen-users] SDL display of HVMs -- how?

Do you have the "sdl=1" option set in your domU''s config
file?

Make sure you have the SDL-devel package installed.

   Yes, I have both of these settings. (Not quite sure what happened
to my original reply to billbaird3 -- it seems to have gone astray).

   I''m running Debian, so I don''t have SDL-devel, but
I''ve installed
every sdl development package I can find, and rebuilt and reinstalled
all the Xen tools and hypervisor from an updated copy of the hg repo.
Still no luck. Where should I be looking for errors or diagnostics?
There''s nothing I can see obviously in the xend log file, for example.

   What program/task is responsible for running the SDL display? Is
there some way of determining what configuration / build options were
picked by the make process?

   Hugo.

   See my later mails -- I''ve done this: installed as many SDL -dev
packages as I can find, and recompiled Xen. Still no luck. How does
Xen determine whether to build with SDL support or not?

SDL is built into qemu, so it is qemu that launches the SDL screen.

Looking at xen-unstable.hg/tools/ioemu/sdl.c I see that it includes SDL.h.

Also check out xen-unstable.hg/tools/ioemu/configure to see how it
determines if the system has the necessary SDL components for building SDL
support.

   OK, thanks. I''ll look into that when I next get time to poke this
(probably Friday).

If you go to $(XEN_ROOT)/tools/ioemu and do "./configure" followed by
"make", then copy the resulting qemu-dm (in i386-dm directory) to the
/usr/lib{64}/xen/bin. Also after "./configure", do "grep -r
CONFIG_SDL".
You should find it in target-i386-dm/config.h [or something like that]. 

I struggled since I rebuilt by build-machine, at first I didn''t have
the
right files installed, and then when I finally got everything in place,
I had vnc=1 also on the machine, and that didn''t work out right. 

Also, have a look at /var/log/xen/qemu-dm.<pid>.log (find the current
one with "ls -ltr /var/log/xen/qemu*" (the newest one is at the
bottom.
[One can probably use "cat `ls -tr /var/log/xen/qemu*`" to show the
latest one, actually - but I haven''t tried that].

   That seems to have done it, finally, after also reconfiguring the
device_model parameter in the domain''s config file. Many thanks.

Related question - is it possible to make the SDL window reappear
after it''s closed?

   My brief experimentation with this seems to indicate that when you
close the SDL window, the VM gets destroyed.

   Hugo.

That is my experience too - I''m not 100% sure if that''s
intended or not.


However, I have also managed to "sink" the window in other ways (like
on
machine0 you ssh to machine1, then ssh to machine2, do "xm create
windows" which pops up a window on machine0, then reboot machine1 for
some reason, and now machine2 has a running windows that you can''t get
to the display of... Most annoying (and it doesn''t take a reboot
either,
just some sort of link loss...).
