[one-users] OpenNebula KVM livemigration problem

[Javier Fontan]

There's a problem with the protocol in the default kvmrc file. Change
in remotes/vmm/kvm/kvmrc the line:

export QEMU_PROTOCOL=qemu

to

export QEMU_PROTOCOL=qemu+ssh

After that issue an onehost sync so that file is updated in the next
monitoring cycle to the nodes, that should solve the problem.

It happens because for libvirt the default communication protocol is
tls so for a remote host qemu is qemu+tls.
