Hola!

I do speak spanish , so if you think spanish will be quicker easier for you, feel free to send me an email

What I do understand from your mail is, at the first boot after vagrant provision the box, a working resolv.conf is there, and all good.

Then, after the reboot, this resolv.conf change and doesn't work anymore for you.

I don't think is going to be any different from virtualbox to vmware on your desktop, but is hard to know if you are on virtualbox/vmware/aws/openstack/docker/lxc :D

For desktop, like vmware/virtualbox the eth0 is NAT, and will use the networking of your laptop, so if the laptop can reach the servers by name, the vm should.
If the laptop can't then, the vm won't.

Dirt fix will be do something like this:

cp /etc/resolv.conf /etc/resolv.conf.ok

echo 'cat /etc/resolv.conf.ok > /etc/resolv.conf' >> /etc/rc.local

but is a hard ugly hack.

if you share more information, I can try to assist to get a better solution and understand the problem.

Saludos!

Alvaro.

Hola Álvaro, buenos días, mi inglés tampoco es muy bueno que digamos, pero vamos a intentarlo ;)

Hello Álvaro, good morning, my english...in't perfect, but lets go to try it!!


Well, i explain my configuration:

I use Vagrant for virtualbox distribution, and im trying to attempt to build a client-server environment, with vagrant and puppet tools, but, for that enviroment booth vm had have dns configuration, with a dns server and dns clients.


to achieve this, its necessary configuration the booth resol.conf files, and that file, with, the vagrant reboot, put me the VAGRANT NAT configuration...

I do not know if I'm explaining it right... I want to have my own resolv.conf configuration, and when i reboot my vagrant vm, my configuration are losed...


Ther's any sugestion? :(

Hola buenos dias Álvaro, muchas gracias por haberme contestado en el google group!!

Estoy intentando hacer una cofngiruación con vagrant, pero me temo, que dicha configuración, no es posible, la quería hacer para presentarla en un proyecto, pero mucho me temo que vagrant, no esta hecho para gestionar arcquitecturas cliente servidor con puppet :(.

Te he contestado en el grupo de google :)

Hello there,

We spoke over gtalk, so I am going to summarize here.

the /etc/resolv.conf in your ubuntu box get modified by the OS, and you tried to stop that and didn't work.

That is not a Vagrant or Virtualbox issue, it's a feature in the OS.

I did send to you a Vagrantfile for Oracle linux 6.5, you can change to use centos

I did test it, and it's what I use for my test case, and PEERDNS=no in /etc/sysconfig/network-scripts/ifcfg-eth0 stop that 

So, give it a try, test it.. you will see it works.

You can install the epel rpm in that vm and use puppet for your test.

http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

something like

config.vm.provision :shell, :inline => "yum install -y http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm"

Feel free to email me if you have issues (mailme directly if you will write in other language rather than english please :) )

Alvaro.
