From 82d4c923a580751c86dc0852a7cc8e369a78e8ad Mon Sep 17 00:00:00 2001 From: Wainer dos Santos Moschetta Date: Fri, 9 Nov 2018 13:21:53 -0500 Subject: [PATCH] Acceptance tests: add Linux initrd checking test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit QEMU used to exits with a not accurate error message when an initrd > 2GiB was passed. That was fixed on patch: commit f3839fda5771596152b75dd1e1a6d050e6e6e380 Author: Li Zhijian Date: Thu Sep 13 18:07:13 2018 +0800 change get_image_size return type to int64_t This change adds a regression test for that fix. It starts QEMU with a 2GiB dummy initrd, and checks that it evaluates the file size correctly and prints an accurate message.
