Diag10 isn't supported under either of these environments so let's
make sure that the test bails out accordingly.
does KVM always implement diag10?
It was introduced October of 2011 and there's no way of disabling it
that I can see.
is there no other way to check whether diag10 is available?
The z/VM CP programming services doesn't specify a feature bit or any
other way to check as far as I can see.
we could, for example, try to run it "correctly" and see whether we get
a Specification exception, and then fence.
We could move the content test to the top and bail out if there's a
spec. That would allow us to handle the addition of diag10 support for
TCG without a test change.
But:
How likely is it that we want to implement diag10 in TCG?
My guess is that adding it to PV is even less likely.
Not running them under PV and TCG gives us back some CI time although
it's likely minuscule.
