Libvirt machine creation in a loop with additional disks

Vagrant

Hello,

I’m trying to create 4 machines in a loop with an additional disk. Here’s what I’ve tried:

Vagrant.configure("2") do |config|

As it turns out, Fedora 34 seems to ship vagrant-libvirt 0.1.2. This was the cause. I removed it and re-installed the plugin using: vagrant plugin install vagrant-libvirt. It works fine now.

I have another problem, though. I cannot use vagrant provision due to some odd bug; documented in vagrant-libvirt’s github README. FYI.
