Public bug reported: On an Ubuntu 19.04 Disco Dingo Beta (both live and installed) Intel GVT-g guest, it was noticed that the graphical interface does not load. The following message appears:
[ 19.844904] i915 0000:00:03.0: Failed to initialize GPU, declaring it wedged! And there are two kernel WARNING that appear. The first WARNING seems harmless and it was already reported: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799102 and is related to the host kernel, on this case 4.18.0-17 from HWE. The second WARNING is new and probably is related to the failure to load the graphics. It is possible to access the guest using the serial console. While the system claims GDM is working, there is no graphical interface visible. I have tested with Xubuntu 19.04 Disco Dingo Beta too and the same problem was noticed: two kernel WARNING, a wedged GPU and failure to load the graphics, even if the LightDM services was shown as running by systemctl status. Ubuntu 18.04 guests with kernel 4.15 and 4.18 are working. Mageia 7 guests with kernel 5.0.7 are working too, this seems related to the 5.0.0 kernel from Disco. Tested with both 5.0.0-7 and 5.0.0-8.
