Hello Guys I have two servers with ovirt 4.1 and I need to make v2v from KVM to Ovirt. When add the new External Provider show me the following error in qemu+ssh://root@IP/system VDSM FQDN command GetVmsNamesFromExternalProvider failed: Cannot recv data: Host Key verification failed. Connection reset by peer Now when add with tcp show me VDSM FQDN command GetVmsNamesFromExternalProvider failed: Unable to connect to server at 'IP:16509' Connection Refused For ssh I run sudo -u vdsm ssh-keygen But i received Permision Denied. How can I resolve this issue Thanks for your help Sebastian

your libvirt is not configured for TCP access
For ssh I run
sudo -u vdsm ssh-keygen But i received Permision Denied.
please paste exactly what you did

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. Alex On Wed, Apr 11, 2018 at 10:36 PM, Sebastian Antunez N. < antunez.sebastian@gmail.com> wrote:
