Warning: Authentication failure. Retrying - centos

Question

I tried
to spin up a CentOS 7 VM. Below is my settings
Vagrant File
# -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.define "zabbix1" do |zabbix1|
zabbix1.vm.box = "centos/7"
zabbix1.vm.hostname = "zabbix1"
zabbix1.ssh.insert_key = false
zabbix1.vm.network :private_network, ip: "10.11.12.55"
zabbix1.ssh.private_key_path = "~/.ssh/id_rsa"
zabbix1.ssh.forward_agent = true
end
end
Result
vagrant reload

What did I do wrong ? What did I miss ?

Answer 1

I had the same issue with the same box and the way I fixed it was to log into the VM from VirtualBox (vagrant/vagrant as username/password) and change the permission of .ssh/authorized_keys
chmod 0600 .ssh/authorized_keys
Do that after you run vagrant up (while the error repeats) and the VM is up and you will see vagrant up will complete successfully and you will be able to ssh into the VM from vagrant ssh

Answer 2

Private networks can be configured manually or with the VirtualBox built-in DHCP server. This works for me.
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.define "zabbix1" do |zabbix1|
zabbix1.vm.box = "centos/7"
zabbix1.vm.hostname = "zabbix1"
zabbix1.ssh.insert_key = false
zabbix1.vm.network :private_network, type: "dhcp"
end
end
Next you have to use vagrant destory and vagrant up.
