I'm hooking Foreman into two servers which run KVM & Libvirt. I'm following 5.2.5
Libvirt Notes
<https://www.theforeman.org/manuals/1.11/index.html#5.2.5LibvirtNotes>, and
I created a SSH Key for testing. I can successfully reach the remote
hypervisors with a command like virsh -c qemu+ssh://hypervisor.example.com/system list.
How do I add the passphrase to Foreman so that Foreman can log in to the
remote server to manage the compute resources? I see some mention of rake
tasks at https://www.theforeman.org/manuals/1.11/index.html#5.2.10PasswordEncryption
, but I'm confused if that applies to what I am trying to do, or how to
encrypt something like a passphrase for libvirt.

If you've set up qemu+ssh so that a password is needed, I'm afraid you'd
have to create a feature request (Issues - Foreman).
You have to change your hypervisor /etc/ssh/sshd_config to allow root
login without-password and ensure your ssh public key is in the
hypervisor /root/.ssh/authorized_keys

that's unrelated, it applies to the password in other compute resources,
libvirt does not have that field.

You don't actually have to use the root user, you can configure policykit
to allow connected to libvirt connection from another user, Google'ing
"libvirt non root user" should help you out there.

We definitely don't want to SSH into servers as root with an unencrypted
key. I'll look into the PolicyKit to allow SSH as another user.
I'll also note that problems with unencrypted keys can be mitigated a bit
by hardcoding a whitelist of allowed commands and IPs in authorized_keys.

Well, that's not quite the right way to phrase it. I'm simply using
qemu+ssh in it's default configuration, and SSH best practices recommend a
passphrase. I was hoping that Foreman would work with this, or would
somehow encrypt a passphrase. I'll look into filing an enhancement request.

I have not specifically tried this in foreman's context, but it should
also be possible to configure sshd to use Kerberos principal based
authentication. For this sshd must be configured to use GSSAPI auth
mechanism and rest is transparent to the applications.
