Vagrant / VirtualBox DNS 10.0.2.3 ne fonctionne pas

ayi

I am running a fresh install of Linux Mint Nadia (14). I am following the instructions on Vagrant <a href="https://www.vagrantup.com/docs/getting-started/" rel="noopener nofollow ugc">Getting Started</a> but have gotten stuck on the <a href="https://www.vagrantup.com/docs/provisioning/" rel="noopener nofollow ugc">Provisioning</a>. It seems the Vagrant box cannot connect outside and so I can’t install anything using either Chef or Puppet.
In the basic Vagrant <code>resolve.conf</code> contains <code>nameserver 10.0.2.3</code>. But with that set I can’t ping <code>us.archive.ubuntu.com</code>.
If I change it to <code>8.8.8.8</code> then I can ping <code>us.archive.ubuntu.com</code> but it does not stay set, and after a reboot it changes back to <code>10.0.2.3</code> - so provisioning fails again.
Ideally I would like for <code>10.0.2.3</code> to work on my setup. Failing that I would like a way to permanently change <code>resolv.conf</code> so that I can do provisioning.

You can work around this issue in one of two ways, both of which are <a href="http://www.virtualbox.org/manual/ch09.html#nat-adv-dns">in the VirtualBox manual</a>:

The NAT engine by default offers the same DNS servers to the guest 
that are configured on the host. In some scenarios, it can be 
desirable to hide the DNS server IPs from the guest, for example when 
this information can change on the host due to expiring DHCP leases. 
In this case, you can tell the NAT engine to act as DNS proxy using 
the following command:
<pre><code class="lang-auto">VBoxManage modifyvm "VM name" --natdnsproxy1 on

</code></pre>

For resolving network names, the DHCP server of the NAT engine offers 
a list of registered DNS servers of the host. If for some reason you 
need to hide this DNS server list and use the host’s resolver 
settings, thereby forcing the VirtualBox NAT engine to intercept DNS 
requests and forward them to host’s resolver, use the following 
command:
<pre><code class="lang-auto">VBoxManage modifyvm "VM name" --natdnshostresolver1 on

</code></pre>
Note that this setting is similar to the DNS proxy mode, however 
whereas the proxy mode just forwards DNS requests to the appropriate 
servers, the resolver mode will interpret the DNS requests and use the 
host’s DNS API to query the information and return it to the guest.
