Subject: [Qemu-devel] [PATCH 3/3] tests/acceptance: Add boot linux with kvm test
Date: Fri, 28 Jun 2019 11:02:17 -0400	[thread overview]
Message-ID: <20190628150217.32659-4-wainersm@redhat.com> (raw)
In-Reply-To: <20190628150217.32659-1-wainersm@redhat.com>

Until now the suite of acceptance tests doesn't exercise
QEMU with kvm enabled. So this introduces a simple test
that boots the Linux kernel and checks it boots on the
accelerator correctly.
