Subject: [PATCH  v2 7/7] tests/avocado: add boot_xen tests
Date: Thu, 11 Feb 2021 17:19:45 +0000
Message-ID: <20210211171945.18313-8-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210211171945.18313-1-alex.bennee@linaro.org>

These tests make sure we can boot the Xen hypervisor with a Dom0
kernel using the guest-loader. We currently have to use a kernel I
built myself because there are issues using the Debian kernel images.
