Vagrant is an application that manages virtualized environments (boxes) allowing to control the creation and provisionning of virtual machines, which may share some resources (folders) with the host.
Vagrant supports different virtualization engines (providers), among which VirtualBox is historically the most popular.
Installation with libvirt
sudo apt install vagrant-libvirt libvirt-daemon-system
Ensure your user is a member of the libvirt group (this is needed to manage libvirt via the qemu:///system uri, which is the default for vagrant-libvirt)
sudo usermod --append --groups libvirt $USER
logout and login so that your group membership applies
# should return libvirt groups | grep -o libvirt
start your first vagrant environment
vagrant init debian/buster64 vagrant up --provider=libvirt vagrant ssh
Debian Vagrant base box
There is an ongoing effort to provide official Teams/Cloud/VagrantBaseBoxes, hosted in Atlas, Vagrant's cloud product, created by Debian Developers.
Creating Debian vagrant boxes
You also may wish to create your own Debian boxes, Debian currently users Packer to build the boxes hosted on the Vagrant cloud.
On vagrant up various errors can happen:
Errors on NFS mount on Debian GNU/Linux jessie and stretch boxes
During the vagrant up process you can get this error on Debian Debian GNU/Linux jessie as well as in stretch:
The following SSH command responded with a non-zero exit status. Vagrant assumes that this means the command failed! mount -o vers=4 192.168.121.1:/home/jhon/projects/foo /vagrant result=$? if test $result -eq 0; then if test -x /sbin/initctl && command -v /sbin/init && /sbin/init 2>/dev/null --version | grep upstart; then /sbin/initctl emit --no-wait vagrant-mounted MOUNTPOINT=/vagrant fi else exit $result fi Stdout from the command: Stderr from the command: mount.nfs: access denied by server while mounting 192.168.121.1:/home/jhon/projects/foo
First of all ensure that your NFS daemon is running:
sudo systemctl status nfs-common sudo systemctl status nfs-kernel-server
Then copy from the above error the mount command and try running it on yourself, but downgrading the NFS version (the vers):
vagrant ssh sudo mount -o vers=3 192.168.121.1:/home/jhon/projects/foo /vagrant
If it works manually, than you can fix it adding this line into your Vagrantfile:
config.vm.synced_folder ".", "/vagrant", nfs_version: "3"
