I'm wondering how this would look when we come to dealing with install
pre-built images. In that case the image may want to be either PV or
FV depending on how the user created it. So adding an option here would
not work too well.
Perhaps we should be asking for the type of install upfront, distro vs
lived, vs pre-built image. I've also been toying around with idea that
instead of asking PV vs FV, we should just ask for the install location,
and then probe that location to figure out whether it has PV or FV
If given a URL http://foo.example/dist/
- Probe for images/vmlinux -> Can do FV with QEMU
- Probe for images/boot.iso -> Can do FV with QEMU or Xen
- Probe for images/xen/vmlinux -> Can do PV with Xen
We could choose FV or PV for the user, or at least give them the
options of what installs are available, based on the media this
pointed to & the host capabilities.
This would suggest a sequence
- Choice of FV/PV options relevant to their media
It would be interesting to explore whether bsaed on Media we can figure
out a simpler way to ask the user whether the ISO was a distro installer
vs a LiveCD ?

I'm not clear why you introduced a 3rd fork for the install media page
when the widgets are identical to those on the FV page. It adds rather
alot more code for no obvious benefit ?

So anyway, interesting prototype - I think we need to play around with
various ideas here..
