Comment 2 for bug 1326536

I created a small patch to place the no-hosts option in the config file which libvirt creates. (I figured that was more appropriate than setting the flag, since all other options are set in those config files by libvirt).

Unfortunately I'm unfamiliar with libvirt's testing suite, and couldn't figure out how to appropriately edit the tests for these changes. It might be best if someone more familiar with the codebase take it from there.

I've also realized that this may be an expected behaviour for some (many users may have placed stuff in /etc/hosts and expect that to work for their VMs). As such, users will need to be warned if this file is excluded by default.

Patch attached.
