Subject: [dpdk-dev] [PATCH] vfio: expand non-viable group error message
Date: Fri, 26 Apr 2019 17:22:30 +0100 [thread overview]
Message-ID: <20190426162230.21158-1-ktraynor@redhat.com> (raw)
"VFIO group is not viable" error message is correct
but not very user friendly for something which can
usually be easily rectified.
Add some additional text to give more of a hint.
Signed-off-by: Kevin Traynor <ktraynor@redhat.com>
