Subject: [PATCH V2 10/23] kvm tools: Add CONSOLE_HV term type and allow it to be selected
Date: Fri, 09 Dec 2011 17:54:20 +1100 [thread overview]
Message-ID: <4EE1B09C.7040902@ozlabs.org> (raw)
In-Reply-To: <cover.1323413420.git.matt@ozlabs.org>
This patch paves the way for adding a hypervisor console, useful on systems that
support one out of the box yet don't have either serial port or virtio console
support (e.g. kernels expecting POWER SPAPR).
