From 171da9d5dbd2fe1ee2f923dff736d89be96c9672 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 16 Nov 2016 09:39:31 +0100 Subject: [PATCH] tests/postcopy: Use KVM on ppc64 only if it is KVM-HV The ppc64 postcopy test does not work with KVM-PR, and it is also causing annoying warning messages when run on a x86 host. So let's use KVM here only if we know that we're running with KVM-HV (which automatically also means that we're running on a ppc64 host), and fall back to TCG otherwise.
