[one-users] MONITOR FAILURE 6 Error executing kvm.rb

[Javier Fontan]

OpenNebula does not need remotes in the frontend to be located in
/var/tmp/one. They are locatrd at /var/lib/one/remotes and copied to
the nodes.

The error you are having look like you have authentication enabled for
libvirt socket connections. These are the parameters I have configured
in /etc/libvirt/libvirtd.conf

--8<------
listen_tls = 0
listen_tcp = 1
unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
mdns_adv = 0
auth_unix_ro = "none"
auth_unix_rw = "none"
------>8--

Most probably the problems are with auth_unix_* configuration, make
sure they say none.

Passwordless ssh configured on all servers for oneadmin account. Also, somehow /var/tmp/one directory was missing on opennebula fron-end server so I copied from one of the kvm hosts. When I try manually run run_probes I get following:
