Re: [ovirt-users] Importing Libvirt Kvm Vms to oVirt Status: Released in oVirt 4.2 using ssh - Failed to communicate with the external provider

Thursday, 8 February 2018

Using the command line on the engine machine (as root) works fine. I
don't use ssh key from the agent GUI but the authentication section (with
root user and password),
I think that it's a bug, I manage to migrate with TCP but I just want to
let you know.

is it possible to use ssh-key from the agent GUI? how can I get the key?

 Hi Maoz,

 it looks like cannot connect due to wrong setup of ssh keys. Which linux
 are you using?
 The guide for setting the ssh connection to  libvirt is here:
 https://wiki.libvirt.org/page/SSHSetup

 May it helps?
