I was hit by this bug when building Virtual Machines for Vagrant.
Not sure if it's a qemu bug or a Debian Networking problem, because if I
stop
the network with
service networking stop
and then request a new configuration with
dhclient eth0
then I get this time a IPv4 DNS entry from the qemu builtin DHCP server.
@manuel: can you confirm this behaviour ?
What would speak for a qemu problem though would be the Qemu 2.7 changelog:
Network
User-mode networking supports DHCPv6, RDNSS, DNS6 and link-local DNS
addresses.
