[PATCH 0/2] osstest: followup from the PVH toolstack series

[Roger Pau Monne]

Hello,

The two patches in this series modify osstest in order to fix the PVH
tests, and also switch HVM guests to use the 'type' option (note that
the builder option is kept for compatibility reasons).

Thanks, Roger.

[PATCH 1/2] osstest: fix PVH DomU tests

[Roger Pau Monne]

The pvh=1 xl option was removed, so switch the PVH tests to use
type='pvh' instead.

[PATCH 2/2] osstest: use type='hvm' for HVM guests

[Roger Pau Monne]

The previous builder='hvm' is also kept for compatibility with older
Xen releases. Note that the type option is ignored in previous Xen
versions.

What will be the effect of this on old Xen branches ?
I think it might stop the pvh tests from working in those branches.

PVHv1 is also removed from the Linux kernel, so it's just a matter of
time until those start failing, if they are not failing already.

This change will just turn the PVH tests into PV test on old branches,
because type=pvh will be ignored and the guest is going to boot in PV
mode.

That's not brilliant.  Can we make this change conditional and/or drop
the pvh tests for older branches ?

IMHO we should drop the PVH tests for older branches (ie: PVHv1
tests). This has already been removed from current Linux and Xen, so
it makes no sense to continue testing them.

Thanks, Roger.
