Bug description:
This might be something simple and known, but I don't find such information... 
I installed qemu 0.12.3 from source on a Linux/x86-64 host and observe that, 
running a debian testing guest (squeeze netinst, also the installed system), 
the DNS setup that qemu's  DHCP provides is not working.

Namely, nameserver 10.0.2.3 in /etc/resolv.conf (as created by DHCP) does not 
help name resolution, but replacing the IP with my actual DNS server does work. 
Now this is still unfortunate as it is very cumbersome to replace the DNS for 
every system I run in qemu for testing... it used to work before with earlier 
versions.

If there is some easy means to help debug this, I'll try to help... but right 
now I am rather clueless.
