I'm trying to connect to another machine using virt-manager (File/Add Connection). I select QEMU/KVM as hypervisor, "connect to remote host", method SSH, and a username and hostname on the remote machine. The result is always that I get prompted for my passphrase, but then see "authentication failed: no agent is available to authenticate". I get this going from either machine to the other.
Virtualization is set up OK because I can run virtual machines on both VM hosts. SSH is set up OK, I can ssh with public key in both directions both as myself and as root. I tried "setenforce 0" on both machines to see if SELinux was blocking it, but the result was the same.
What am I missing?

Do you see the process ssh-agent running?

Right, do you see your identity there? $ ssh-add -l
If so, is there any chance of you are running the virt-manager out of the established session? I'd start the virt-manager on the same shell running the ssh-add above to confirm.
I just tried here with F21 and I could add a remote hypervisor using ssh keys.

I finally got some more time to work on this. At first, it seemed like a KDE thing, as "ssh-add -l" didn't show anything when I first logged in. So I added ssh-add to the list of startup programs, and now the KDE version of ssh-askpass prompts me for a password when I log in, and I can ssh to the remote machine without entering a passphrase for the key. But I still get the same error when I try to create a new KVM connection! Anybody have any other ideas?

Great, glad I could help.
BTW, the Cookbook is WIP and not formally published because there isn't a lot of content yet. Contributions welcome :)
