From 1e7398a140f7a6bd9f5a438e7ad0f1ef50990e25 Mon Sep 17 00:00:00 2001 From: Pankaj Gupta Date: Tue, 16 Jun 2015 13:48:59 +0530 Subject: vhost: enable vhost without without MSI-X We use vhostforce to enable vhost even if Guests don't have MSI-X support and we fall back to QEMU virtio-net. This gives a very small performance gain, but the disadvantage is that guest now controls which virtio code is running (qemu or vhost) so our attack surface is doubled. This patch will enable vhost unconditionally whenever it's requested. For compatibility, enable vhost when vhostforce is set, as well. Signed-off-by: Pankaj Gupta Reviewed-by: Michael S.
