The idea behind our use of vagrant is to provide a quick way to get a basic NVMe enabled sandbox going without the need for any special hardware. The vagrant environment for SPDK has support for Ubuntu 16.04 and Centos 7.2. This environment requires vagrant 1.9.4 or newer and VirtualBox 5.1 or newer with the matching VirtualBox extension pack.
The VM builds SPDK and DPDK from source which can be located at /spdk.
Note: If you are behind a corporate firewall, set http_proxy and https_proxy in your environment before trying to start up the VM. Also make sure that you have installed the optional vagrant module 'vagrant-proxyconf'.
This vagrant environment creates a VM based on environment variables found in ./env.sh To use, edit env.sh then
cd scripts/vagrant
source ./env.sh
vagrant up
At this point you can use "vagrant ssh" to ssh into the VM. The /spdk directory is sync'd from the host system and the build is automatically done. Other notable files:
build.sh : is executed on the VM automatically when provisioned
Vagrantfile : startup parameters/commands for the VM
The few commands we mention here are enough to get you up and running, for additional support just use the vagrant help function to learn how to destroy, restart, etc. Further below is sample output from a successful VM launch and execution of the NVMe hello world example application.
vagrant --help
By default, the VM created is/has:
- Ubuntu 16.04
- 2 vCPUs
- 4G of RAM
- 2 NICs (1 x NAT - host access, 1 x private network)
Currently only the Virtualbox provider is supported.
The following shows sample output from starting up a VM and running the NVMe sample application "hello world". If you don't see the NVMe device as seen below in both the lspci output as well as the application output you likely have a VirtualBox and/or Vagrant versioning issue.
