How can I make a VirtualBox VM use the host's DNS?


amphibious

I use VirtualBox for my VM. My office network setup is wireless, i.e. I'm connected to a company WiFi network which has a local DNS for resolving local names (eg something.mycompany.com pointing to 123.45.67.89 ). When I build a new VM, it can connect to the external internet, inheriting the host's connection, but cannot resolve local names using local DNS. So /etc/hostsafter resolving the name on the host, I have to go into the VM and make an entry manually, which is annoying.

Is there a way to make VirtualBox automatically connect the guest to the host's DNS so I don't have to do this manual step? My host is OSX Mountain Lion and the virtual machine is usually Ubuntu, but I doubt it matters.

To enable DNS proxy mode using the host's resolver , run the following command:

VBoxManage Modifyvm“ <VM名称> ” --natdnshostresolver1

As a result, the host DNS API will be used to intercept and resolve guest OS DNS requests, rather than having the guest OS connect to an external DNS server like that --natdnsproxy1 on.

You can get the name of the VM by running VBoxManage list runningvms.
