[Xen-users] vnc not working for iso install

[Christian Schneider <christian.schneider@xxxxxxxxxxxxxxx>]

Hey,
I am trying to install am vm from iso but it doesn't work.

Problem:
Gvncviewer just shows me a black screen (in case of a kali.iso). Booting
from Win7.iso I get the loading screen for about 3 seconds, then the
screen gets black, too. Using vnc on an installed vm works without a
problem.

Because of using a Skylake CPU I am using xen 4.6 from debian strech

I tried enabling sdl and different vncclients. I can make a video if you
want to see it. Running  xl -vvv create win7.cfg I get:
....

libxl: debug: libxl_dm.c:1780:libxl__spawn_local_dm:
/usr/bin/qemu-system-i386
libxl: debug: libxl_dm.c:1780:libxl__spawn_local_dm:   -xen-domid
libxl: debug: libxl_dm.c:1780:libxl__spawn_local_dm:   94
....

Doesn't qemu-system-i386 looks a bit strange?


Thanks, Christian
