[Pkg-xen-devel] Bug#776742: xen-utils-common: no support for VGA Passthrough

Brian Paterni bpaterni at gmail.com
Sun Feb 1 01:52:01 UTC 2015 

For reference, I've attached the xl domU configuration I'm working with
along with verbose output of xl create with the error messages I'm seeing

xlcreate-nogfxpt: #gfx_passthru=0
xlcreate-gfxpt:   gfx_passthru=1
xlcreate-gfxpt-dm-traditional:
                  gfx_passthru=1
                  device_model_version="qemu-xen-traditional"

For further reference, here are a few bugs I've found which may be
related to this problem:

#688311 -- xen-utils-4.2: qemu-dm not available
    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=688311
#733865 --  xen-utils-4.3: qemu-dm is not executable: No such file or
directory
    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733865
#746156 --  libvirt-bin: Wrong parameters for qemu-dm
    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746156
