Subject: [Qemu-devel] [PATCH] virtio-pci: Report an error when msix vectors init fails
Date: Mon, 23 Jun 2014 17:06:25 +0800 [thread overview]
Message-ID: <1403514385-9312-1-git-send-email-famz@redhat.com> (raw)
Currently vectors silently cleared to 0 if the initialization is failed,
but user should at least have one way to notice this.
