Subject: [PATCH] xen: use hvc console for dom0
Date: Mon, 26 Feb 2018 12:08:22 +0100 [thread overview]
Message-ID: <20180226110822.13787-1-jgross@suse.com> (raw)
Today the hvc console is added as a preferred console for pv domUs
only. As this requires a boot parameter for getting dom0 messages per
default add it for dom0, too.
