Checklist

[ ] Is your issue/contribution related with enabling some setting/option exposed by libvirt that the plugin does not yet support, or requires changing/extending the provider terraform schema?
- [ ] Make sure you explain why this option is important to you, why it should be important to everyone. Describe your use-case with detail and provide examples where possible.
- [ ] If it is a very special case, consider using the XSLT support in the provider to tweak the definition instead of opening an issue
- [ ] Maintainers do not have expertise in every libvirt setting, so please, describe the feature and how it is used. Link to the appropriate documentation
[X] Is it a bug or something that does not work as expected? Please make sure you fill the version information below:

Description of Issue/Question

Until today I was using version 0.6.3 of the libvirt provider and everything was working fine. I decided to update to version 0.6.12 and that's what I got. terraform init worked flawlessly.

Setup

terraform {
 required_version = ">= 0.13"
  required_providers {
    libvirt = {
      source  = "registry.terraform.io/dmacvicar/libvirt"
      version = "0.6.12"
    }
  }
}

provider "libvirt" {
  uri = "qemu+ssh://root@${var.libvirt}/system?socket=/var/run/libvirt/libvirt-sock"
}

Steps to Reproduce Issue

Running a terraform plan this is what I get:

Error: failed to dial libvirt: ssh: handshake failed: knownhosts: key is unknown
│
│   with provider["registry.terraform.io/dmacvicar/libvirt"],
│   on main.tf line 11, in provider "libvirt":
│   11: provider "libvirt" {

Partner and community providers are signed by their developers.
If you'd like to know more about provider signing, you can read about it here:
https://www.terraform.io/docs/cli/plugins/signing.html

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
