Subject: [Qemu-devel] [PATCH] s390x: fix -initrd in virtio machine
Date: Wed, 19 Sep 2012 17:29:38 +0200 [thread overview]
Message-ID: <1348068578-24375-1-git-send-email-agraf@suse.de> (raw)
When using -initrd in the virtio machine, we need to indicate the initrd
start and size inside the kernel image. These parameters need to be stored
in native endianness.
