** Description changed: In Ubuntu 12.04, the way networkmanager now defaults to using dnsmasq as a local resolver seems to break many VM configuration using VirtualBox, because VirtualBox's DHCP server tries to inherit the host's DNS configuration and provide it to the guest. In the default configuration, the only DNS server visible to applications is the dnsmasq server, which is accessable only from localhost. The end result is that a virtual machine that configures networking via DHCP will inherit no working DNS servers, resulting in reconfigured DNS in the guest. + + [Impact] + DNS doesn't work in guests + - when it uses the DNS server from the DHCP response and + - the host uses networkmanager + + [Test Case] + Running "host ubuntu.com" on the command line fails. + + [Development Fix] + Fixed during Raring cycle. + + [Stable Fix] + Is being fixed in 4.1.12-dfsg-2ubuntu0.3 upload to precise-proposed and + 4.1.18-dfsg-1ubuntu1.2 upload to quantal-proposed. + + [Regression Potential] + We should verify that DNS in guests still works when the host + doesn't use networkmanager.
