Hi Sebastian,

In case you would like to use SSH you need to setup SSH keys for vdsm user of at least one of the ovirt hosts in order to SSH from it to the remote KVM host (lets name it kvmhost) as below:

1. Edit temporarily the /etc/passwd of one host of your ovirt cluster. (say node0 for example) and replace /sbin/nologin with /bin/sh for vdsm user as below:

vdsm:x:36:36:Node Virtualization Manager:/var/lib/vdsm:/bin/sh

2. Switch to vdsm user and generate SSH keys:

su - vdsm

ssh-keygen

ssh-copy-id root@kvmhost

verify that you have passwordless SSH from node0 (ovirt host) to your KVM host

restore previous /etc/password (replace /bin/sh with /sbin/nologin for vdsm login shell)

3. Go at ovirt GUI and at VM import use the URI: qemu+ssh://root@kvmhost/system

replace kvmhost with your IP and use as proxy host the one that you configured SSH keys (node0 at this example).

This should work as for me it is working.

In case you login with another user and not root, you may do so as long as the user has proper permissions for libvirt/qemu.

For TCP URI you need to enable TCP socket at kvmhost.

your libvirt is not configured for TCP access
