From 1ea04d87525f26c2cd32ba29c0f14c6226f60729 Mon Sep 17 00:00:00 2001 From: Jason Wessel Date: Thu, 23 Jan 2014 08:32:46 -0600 Subject: runqemu, runqemu-internal: Allow slirp for NFS and KVM use The default slirp address for the NFS server is 10.0.2.2. If not using a tap interface this address must be used or the target system cannot connect properly. Also the ip=... kernel arguments need to be set to dhcp when using slirp or the root NFS will not get setup properly. The call to cleanup() results in a routine which is not defined when setting up the NFS because it is called before acquire() for the locking of the tap interfaces, the solution being to simply not call cleanup() that early. When using slirp, kvm should not execute the vhost net checks because the vhost net will not be configure or used.
