      libvirt-1.2.8-16.el7_1.4.x86_64

      at Jenkins host:
      libvirt 1.2.8

      libvirt-0.4.7.jar

      I am able to do a "virsh connect qemu+ssh:" command line and is able to get console.

      While configuring if do not select "Use Native Java libvirt client" then, then during testing the connection I am getting the below error.
      org.libvirt.LibvirtException: Cannot recv data: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password). : Connection reset by peer

      At the same time the daemon prints no messages (/var/log/messages at host).

      But if "Use Native Java libvirt client" is selected then, I could see messages like below at the host.

          please provide more configuration details
          jenkins and plugin versions, credentials type used (i.e. user+password or ssh key)
          also please test plain ssh connection and paste debug output (ssh -v ...), make sure you are testing as the jenkins user

          thanks

          As I mentioned earlier, ssh is working fine(see output below). After adding the key to store, the plugin started working. I think this should be documented or else plugin should be enhanced to accept external passwords.

          vagrant@webdev:~$ virsh -c qemu+ssh://root@X.X.X.X/system list --all
          root@X.X.X.X's password:
          Id Name State
          ----------------------------------
          406 laa_6wind running

          • 6wind shut off
          • generic-app shut off

          vagrant@webdev:~$

          can you make a suggestion were should what exactly be documented ?
          when you configure the cloud you also need to configure credentials, is that too hidden away in the UI? also what do you mean with accepting external passwords ?

          I am still facing the issue with Centos 6.5 , Centos 7 and Ubuntu 14.04

          virsh -c qmue+ssh://root@servername/system list – works fine from commandline
          tried all possible combincation of credentials with both username/password and ssh name/phasphrase.

          Have already setup the password less ssh between my jenkins server and the hypervisor still facing the issue with the plugin.
