I can't get vagrant working with libvirt.

I first used the distro packages, but it produced the same error you see in my description below. Then I removed every distro vagrant package and installed the packages provided by hashicorp:

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
sudo apt-get update && sudo apt-get install vagrant

then I installed the libvirt-vagrant plugin:

vagrant plugin install vagrant-libvirt
Installing the 'vagrant-libvirt' plugin. This can take a few minutes...

Fetching fog-xml-0.1.4.gem

Building native extensions. This could take a while...
Fetching fog-libvirt-0.9.0.gem
Fetching vagrant-libvirt-0.7.0.gem
Installed the plugin 'vagrant-libvirt (0.7.0)'!

However the vagrant up --provider=libvirt still fails:

The provider 'libvirt' could not be found, but was requested to
back the machine 'debian11'. Please use a provider that exists.

Vagrant knows about the following providers: virtualbox, hyperv, docker

Any ideas?

So I tried this process on a fresh VM but these are the steps I followed(In my testing I felt libvirt storage is very slow, is it due to my hardware or it is expected ?)

The Steps I followed


 curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
 sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
 sudo apt-get update && sudo apt-get install vagrant

 apt install vagrant-libvirt
 apt-get build-dep vagrant ruby-libvirt
 apt-get install qemu libvirt-daemon-system libvirt-clients ebtables dnsmasq-base
 apt-get install libxslt-dev libxml2-dev libvirt-dev zlib1g-dev ruby-dev
 apt-get install libguestfs-tools
 vagrant plugin install vagrant-libvirt
 
 vagrant init fedora/32-cloud-base
 vagrant up --provider=libvirt

Well I am doing this all in a cloud VM, while doing up I got errors like Error while creating domain: Error saving the server: Call to virDomainDefineXML failed: End of file while reading data: Input/output error I hope it's no relevant to your query.

Hope it helps.

  • Cloud VM's don't always support "nested virtualization" (Running a VM in a VM). (because the Cloud VMs are VMs, they can't always run VMs. Many cloud providers offer bare metal Infrastructure as a Service for doing VM things) Commented Feb 22, 2022 at 20:28
