Subject: [PATCH 0/2] virtio: recover from vector assignment failure
Date: Thu, 23 Jul 2009 18:45:22 +0300 [thread overview]
Message-ID: <20090723154522.GA13965@redhat.com> (raw)
This patch series fixes a regression reported by Amit Shah
(see Subject: Re: qemu-kvm missing some msix capability check,
Message-Id: 20090723142550.GA4470@amit-x200.redhat.com)
Since Amit's testing, I have refactored the change slightly to make the
patch smaller.
Rusty, can this go in for 2.6.31, or do you think it's too big a change?
As an alternative work-around, we possibly could do something in qemu in
host to make it less likely that mapping vq to vector fails - but it
seems that we still want the guest to handle the error as gracefully as
possible, right?
