The current virtualbox code is limited to a single DNS proxy, thus the
"ignored" messages for any configured DNS server but the first. This can
be fixed of course, but it's currently not very high priority.

The slirp code needs to be improved to support more than one DNS proxy.
The DNS proxy is necessary as it's impossible to synchronize the DHCP
lease lifetime with the host's DNS server information validity if the
host itself uses DHCP and/or several IP links.
