Unknown configuration section 'hostmanager'.

[dbstraffin]

Using vagrant 2.1.3 and vagrant-hostmanager 1.8.8 and 1.8.9, I get the following error:

There are errors in the configuration of this machine. Please fix
the following errors and try again:

Vagrant:
* Unknown configuration section 'hostmanager'.

I tried vagrant plugin update, vagrant plugin repair and vagrant plugin expunge, none of which fixed the issue.

Downgrading to vagrant 2.1.2 fixed the issue and people are having issues with other plugins, so it might actually be a problem with vagrant 2.1.3.

Hi there,

This was a Vagrant issue and was fixed via hashicorp/vagrant#10155

Looks like Vagrant 2.1.4 fixes this issue for me.

Solutions:

Step one:
On your host machine you need to install VirtualBox and the VirtualBox is a hypervisor that helps you to build Virtual Machine.

Step two:
If you have Hyper-V hypervisor in your PC, first, you disable it.
Right-click > Windows Power Shell > Run as administrator > Copy the Below command

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

*execute the code with power shell and Your Hyper-V will disable

Step three:
Download the Vagrant installer and install it on your windows machine.

Step Four:
Now you can execute your “vagrant up” Command using Git Bash. Just type the following command to verify Vagrant.
$ vagrant --version
$ git --version
Step Five:
Need to install the Vagrant plugin. Execute the below command by Git Bash
$ vagrant plugin install vagrant-hostmanager

And finally, execute this one.

`$ vagrant up`

vagrant-hostmanager is a Vagrant plugin that manages the host's file on guest machines (and optionally the host). Its goal is to enable the resolution of multi-machine environments deployed with a cloud provider where IP addresses are not known in advance.

$ vagrant plugin install vagrant-hostmanager

This Work for me!!!!

To update the host's file on each active machine, run the following command:

$ vagrant hostmanager
