Installer update request for completing
[19.04 FEAT| Enable virtio-gpu for s390x
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799467

Addl description:
The graphical installers either require VNC to be set up on s390x to run or are not supported at all.

With virtio-gpu support the installers can start an X Windows server locally as they would on an x86 system.

The distributor most likely only needs to disable s390x specific handling in the installer (like starting a VNC server) and just launch the graphical UI used for installation if a virtio-gpu device is present.

Business Value: Allows to install s390x KVM guests without any extra setup activities, providing the same user experience as on other platforms.

Since graphical components are not supported by the Ubuntu Server distribution and since we follow a different philosophy on things like this, I'm marking this as Invalid and suggest to have a quick call on that.

Since this is the line item entry of the technical bug LP 1799467,
and since it is not about virtio-gpu CPU in QEMU rather than having a guest kernel support enabled so that an Ubuntu - when running on an enabled qemu - can actually output anything,
this is dependent and therefore tracked in LP 1799467 (it's not really a duplicate).
Since LP 1799467 is Fix Released, I'm setting this to Fix Released as well.
