I found that a fix for this was comitted upstream quite recently, cherry
picked this to artful and it resolves the issue in my testing. Now
applied to artful/master-next.

So I think I can now at least explain the weirdness. Booting from the
ISO as well as the first boot in OEM mode seem to be in a way where grub
does not use graphics mode and hands that off to a vt. In that case,
when the kernels starts there will be no VESA framebuffer which later
gets switched ove

Hm, would be good if you noted down more exactly which version/ppa. I
assume it is the mainline builds and likely 4.14~rc2.

This bug is also reproducible with the end user stage of an OEM
installation which runs ubiquity-dm like a boot from an ISO.
I think 4.14 (from Canonical kernel team's ppa) fixes the issue. I
installed this kernel during the OEM prepare stage, then the image boots
fine during the end user setup.

Unfortunately I don't seem to have access to the latest images and this
happening only when booting the ISO makes it hard(er) to grab data. I
did finally succeed by using "virsh dump --memory-only "
and then "sudo strings |less". And it looks like the qxl drm

@bdmurray, I'd like you to reconsider the notfixing tag, it's a real
issue for QA because qxl is the only driver that works with wayland. The
system falls back to X with the standard vga driver and does not boot
after installation with cirrus.

It happens even if you start a VM directly with qemu from the command
line with the qxl driver (option -vga qxl) independently of virt-
manager.
For example, the following command will hang on boot:
/usr/bin/qemu-system-x86_64 -m 2G -smp 2 -localtime -no-reboot -cpu core2duo
-enable-kvm -drive fi

I can confirm the issue and dup'ed bug 1714638 onto this where people assumed
first it would be an error in the virst stack.
>From there TL;DR:
- works with cirrus/vga, but not qxl
- works if nosplash is set
- works on Xenial but not on Artful
