This is on top of my previous patch fixing vmgenid.
PPC PXE test is reported to be especially slow - does anyone care to try
it and measure whether this helps?

NACK.
It's not that simple. If you do it like this, you then suddenly get
these ugly '"kvm" accelerator not found' messages during "make check"
which we really should avoid.
Laurent suggested some better ideas a couple of months ago, but I think
the common sense was rather "unit tests should always use TCG" at that
point in time:
https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg00400.html
Well, now that we've got the "--disable-tcg" configure option, we should
maybe start to reconsider that ;-)
So I'm fine with the patch if you also include Laurent's patch to shut
up the error message:
https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg00395.html

You're right, I thought these were shut up before with Laurent's patch. I think we should print a single message at the end, like qemu: -machine accel=kvm:xen: No accelerator found Paolo > Laurent suggested some better ideas a couple of months ago, but I think > the common sense was rather "unit tests should always use TCG" at that > point in time: > > https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg00400.html > > Well, now that we've got the "--disable-tcg" configure option, we should > maybe start to reconsider that ;-) > > So I'm fine with the patch if you also include Laurent's patch to shut > up the error message: > > https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg00395.html > > Thomas >

As a rule, don't send nacks please. Skip directly to the technical
argument. Nacks add very little to the discussion and tend to scare away
contributors. All upper case also looks like shouting. That's unlike
acks which include reviewer's name and can be recorded in git history so
people know whom to ask questions about a commit.

Looks good. This was never posted as a patch. Would you or him care
to test it and re-post? I'll include it with my patch.

I hope I won't scare *you* away that easily ;-)
But ok, I got the message, and will try to remember it.

That URL points to Paolo's "we should always only use TCG mail" ... I
guess you are rather referring to the other URL below?
