Bug description:
  In disco, xorg stopped shipping a cirrus module/driver, instead
  relying on the kernel one. But the kernel one is in the linux-modules-
  extra-<version>-generic package, which is not installed by default in

  That breaks some assumptions: uvtool, for example, doesn't specify a
  video device when creating a vm, and the default in libvirt in such
  cases is to use cirrus. As a conseguence, disco VMs created by tools
  that do not specify a default video device  won't have the cirrus.ko
  module, and X won't start there.

  It's a bit more complicated, however, because X just tries other
  fallbacks, but they also don't work. In particular, vesa doesn't work:

  We can change uvtool and specify a video device instead of leaving it
  blank (see bug #1818877), but there might be other tools out there
  spawning guests without telling them which video device to use, and
  they would also fail.
