[Qemu-commits] [COMMIT 25fe365] virtio-pci: return error if virtio_conso

Subject: [Qemu-commits] [COMMIT 25fe365] virtio-pci: return error if virtio_console_init fails
Date: Mon, 05 Oct 2009 14:53:34 -0000

From: Amit Shah <address@hidden>

Currently only one virtio_console device is supported. Trying to add
multiple devices fails and such failure should be reported back to the
qdev init functions.
