This is always indicative of a bug within the plugin. It would be immensely helpful if you could report the crash with the plugin's maintainers so that it can be fixed. The output above should help diagnose the issue.

Setup

provider.tf file

provider "libvirt" {

uri = "qemu:///system"

uri = "qemu+ssh://IP ADDRESS/system?keyfile=/root/.ssh/ssh_priv&sshauth=privkey" }

Private ssh key have been provisioned with a before_script entry just before calling the "plan" command

[jbhfenris]

Not an issue. Problem of copy ssh private key at the correct format on the gitlab-ci runner.
