Bug Description

Because of the following patch:

  Subject: [PATCH 2/2] libxl: Fix up VRAM to minimum requirements

  This is a bit debatable. On one side it hides configuration errors
  in a way that makes them hard to spot. On the other side there is
  at least one issue with (maybe some older versions) virt-manager.
  Virt-manager sets VRAM directly, not using the default memory setting
  but uses too small values for libxl. Worse, those versions do not seem
  to allow to change VRAM from the GUI. So switching the video type to
  VGA makes the guest fail to start until one manually adapts the VRAM
  size in the XML definition.
  With this change this would not happen but VRAM will be bigger than
  the GUI says. This would not be that different from current Cirrus
  behaviour. Only that in that case qemu seems to ignore the provided
  size.

and possibly some default Werror= change in newer GCCs, we can't recompile cleanly libvirt in Ubuntu Disco, facing the following error:

libtool: link: ( cd ".libs" && rm -f "libvirt_driver_lxc_impl.la" && ln -s "../libvirt_driver_lxc_impl.la" "libvirt_driver_lxc_impl.la" )
../../../src/libxl/li bxl_conf.c: In function 'libxlMakeVideo':
../../../src/libxl/libxl_conf.c:2393:13: error: enumeration value 'LIBXL_DEVICE_MODEL_VERSION_UNKNOWN' not handled in switch [-Werror=switch-enum]

My patch is fixing this issue by patching the previous patch.

While the patch is "correct" there is no issue like that "in Disco".

It only affects custom build environments.
I have built libvirt in Disco in a PPA today and it worked fine (PPA deleted again).

Setting Won't Fix on this one.

Thank you, sorry for the noise. Will fix here.
