From e80e2a60ff7914dae691345a976c80bbbff3ec74 Mon Sep 17 00:00:00 2001 From: Sridhar Samudrala Date: Tue, 30 Mar 2010 16:48:25 -0700 Subject: [PATCH] KVM: Increase NR_IOBUS_DEVS limit to 200 This patch increases the current hardcoded limit of NR_IOBUS_DEVS from 6 to 200. We are hitting this limit when creating a guest with more than 1 virtio-net device using vhost-net backend. Each virtio-net device requires 2 such devices to service notifications from rx/tx queues.
