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?
