Installing Vagrant

Installing Vagrant is extremely easy. Head over to the Vagrant downloads page and get the appropriate installer or package for your platform. Install the package using standard procedures for your operating system.

The installer will automatically add vagrant to your system path so that it is available in terminals. If it is not found, please try logging out and logging back in to your system (this is particularly necessary sometimes for Windows).

Looking for the gem install? Vagrant 1.0.x had the option to be installed as a RubyGem. This installation method is no longer supported. If you have an old version of Vagrant installed via Rubygems, please remove it prior to installing newer versions of Vagrant.

Beware of system package managers! Some operating system distributions include a vagrant package in their upstream package repos. Please do not install Vagrant in this manner. Typically these packages are missing dependencies or include very outdated versions of Vagrant. If you install via your system's package manager, it is very likely that you will experience issues. Please use the official installers on the downloads page.

If You're Running Other Virtualizers on Linux

On some systems you may get the following error when running Vagrant commands:

There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", <ID of the VM>, "--type", "headless"]

Stderr: VBoxManage: error: VT-x is being used by another hypervisor (VERR_VMX_IN_VMX_ROOT_MODE).
VBoxManage: error: VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot
(VERR_VMX_IN_VMX_ROOT_MODE)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

This is because another virtualizer (like KVM) are in use. We must blacklist these in order for VirtualBox to run correctly.

First find out the name of the virtualizer:

$ lsmod | grep kvm
kvm_intel             204800  6
kvm                   593920  1 kvm_intel
irqbypass              16384  1 kvm

The one we're interested in is kvm_intel. You might have another.

Blacklist the virtualizer (run the following as root):

# echo 'blacklist kvm-intel' >> /etc/modprobe.d/blacklist.conf

Restart your machine and try running vagrant again.
