[one-users] can't livemigrate VMs

[samuel]

the kvmrc file on opennebula is not used by the nodes so you shall change
/var/tmp/one/vmm/kvm/kvmrc on every node where kvm is running.

After that change, in the error log you shall see connecting to uri:
qemu+ssh:// instead of quemu://

About the other error, failed to connecto to the hypervisor, I can not help
much but it seems as if there is no hypervisor running and you should check
the installation and the running processes on all nodes.

I'm sorry I cant not help further,

Samuel.
