Networking error when starting vagrant machine.

[jiminfote...@gmail.com]

Hello Folks,

I ran into the following error when I execute "vagrant up" command.

The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network.

Vagrant file:
Vagrant.configure("2") do |o|
o.vm.box="centos/7"
o.vm.network "private_network", ip: "192.168.1.13"
o.vm.provision "shell", :path=>"setup.sh"
end

setup.sh:
sudo yum -y update
sudo yum -y install vim,git,gedit,nmap
sudo systemctl restart httpd

Nothing is started but I see a machine in Virtual box and I double click and I start as usual. Could assign static IP but no network to outside world. Not sure where the things are going wrong.

Any help would be very much appreciated.

Thanks
Jim

Hello,

the message is telling you that ip network can be used for private network because there is a network that already exists.

you can use a different network, or try wirth public if what you want is the vm to connect to 192.168.1.x

Hi Alvaro,

It works with public_network but I don't have access to internet as I see two active interfaces eth0 and eth1. Can we make it working with only one interface ? How to do that?

Cheers
Jim

P.S: Not at all happy with "Vagrant" product. No offence..............

Hello,

Vagrant does one job and does it very nice. Time by time people want to make vagrant what they would like to do, instead of learning a bit of Vagrant, and that create fustration.

1. Vagrant always will use eth0 for local host/vm communication, and over this network you can use the forwarder ports, and the VM will have access to the network using nat.

2. When you add a private network, you can use this IP (fixed or dhcp) to ssh into the VM, VM->Host, or in a multi machine setup to VM->VM

3. When you use public network, you will get an IP from your home/office network, and by default, its documented, Vagrant wont override the default GW. So if you need to do this, there is an example script in the documentation on how to do this.

IF you could share what you want to do, how your Vagrantfile looks like, there is a lot of people that can have a look and share ideas with you.

Thanks

Alvaro.

Hi Alvaro,

I have invested days in learning vagrant but somehow not yet in comfort zone. What I find interesting is that I did "vagrant destroy" and then did "vagrant up" and everything seems to be working fine even thought loop back, eth0 and eth1 are all UP.

My Vagrantfile contents was in my original post., anyway posting it again:

Vagrant.configure("2") do |o|
o.vm.box="centos/7"

o.vm.network "public_network", ip: "192.168.1.13"

o.vm.provision "shell", :path=>"setup.sh"
end

setup.sh contents:
sudo su - root
yum -y update
yum -y install vim git gedit nmap
yum -y install httpd
systemctl restart httpd

Not sure why vagrant is not able to install packages??

vagrant up log output is below, I don't think I anything wrong with my Vagrantfile or setup file.

P.S: I realized why I have two interfaces as there is two adapters ! My mistake for sure.

Would wait to hear from learned people why package installation is not working.

Hello the script is not correct.

ITs ok as a series of command that someone need to type, but as soon as sudo su - happens the script should wait for ever, or exit and continue, not sure. But you can skip that line and all the sudo.

Vagrant will run the commands as root (by sudo), so your script should be like this,

setup.sh:

yum -y install vim git gedit nmap

systemctl restart httpd

Do not run yum upgrade, since that will upgrade the kernel and that will cause issues with virtualnbox and other modules.

Options:

a. Create a new base box that is fully updated (fit for use)

b. Update what you require and expclude kernel, ie. yum upgrade -y --exclude kernel*

Thanks

Alvaro

Hi Alvaro,

Still it doesn't do any installation. I think the two adapters are because of 1. default public network and 2 because I want private network with static IP.

Output from vagrant up is below.

Content of setup.sh
yum -y upgrade  --exclude kernel*

yum -y install vim git gedit nmap
yum -y install httpd
systemctl restart httpd

[Alvaro Miranda Aguilera]

hello,

the message is telling you that the box was already provisiones, so it wont run the commands again,

you can run vagrant provision, or vagrant up --provision, or just destroy and create a new one.

In that way you will be forcing a new provision.

Thanks

Alvaro.

Hi Alvaro,

It seems my happiness was for only short while.

I delete the machine by vagrant destroy, deleted the folder and recreated another folder, placed the previous Vagrantfile and now having like here:
https://github.com/mitchellh/vagrant/issues/7610

It's not fixed in Vagrant 1.8.5 I had to chmod into VM and then its working fine.

Cheers,

Jim

thats more related to the guest.

add config.ssh.insert_key=false and try again from vagrant destroy as time permits.

Alvaro.
