This is probably an extreme edge case, so it is understandable if the functionality is not desirable...
I have a guest that runs Xen which requires a hostonly interface, but the guest interface (eth1) should not be configured by Vagrant because the guest interface should be part of a bridge:
iface eth1 inet manual
iface xenbr0 inet static
dns_nameservers 22.214.171.124 126.96.36.199
post-up route del default gw 192.168.56.1; route add default gw 192.168.56.1 metric 100;
Currently, I'm managing the hostonly interface with modifyvm, but I will need to add a lot of ruby logic to create the hostonly network if it doesn't exist, set the IP address, etc.
website/docs: update docs for auto_config [GH-3015]
This is already a feature, just specify auto_config: false as an option. I've added it to the docs now (will deploy with next version release).
Nice!!! Many thanks.
