NAT DNS Proxy Option?

[devans]

I've spent a few days trying to isolate the cause of really bad instability (I'd only get through the whole up process, including chef provisioning, a fraction of the time) with a Win 7 x64 host and Ubuntu 12.04 32-bit guest. I finally got it down to the NAT DNS proxy option in the sane defaults.

Basically the host Ubuntu would run for a while then crash hard before finishing the bootstrapping process. I noticed it was usually associated with network transfers (i.e. lots of apt-gets in Chef). I checked out #909 (but it seems like that discussion had more to do with Ubuntu 12.04 hosts?). Finally I ended up manually turning off --natdnsproxy1 in my Vagrantfile, and suddenly everything's humming along fine.

I'm wondering if anyone has any more insight into why this was happening, and also to raise the question of whether there should be an option in the Vagrant config object to turn it off.

I don't quite understand why this is happening and maybe the NAT DNS proxy is in fact NOT a sane default. Anyways, I've made a change to allow disabling this. More here: #1313
