| Stephanie Daugherty (sdaugherty-deactivatedaccount) wrote networkmanager+dnsmasq implementation seems to break DNS resolution for virtualbox VMs | #0 |
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.
