[Qemu-devel] patch for smb/user-net with no network

Hi,

On OSX, I use user-net and qemu does not start when I am not connected 
to the network unless you do specify -nics 0. It exits when it does not 
find a DNS.

However, I use my SAMBA service to mount host partitions, so I would 
like to have the network start.

This patch sets the DNS to the local address when none is found so I 
can still use the net when host is not on the network.

Rgds,
