[one-users] can't livemigrate VMs

[Khoa Nguyen]

Hi samuel!
Change the file kvmrc on opennebula or kvm ?
the fist time , I have just change the file kvmrc on opennebula.
file path is
/srv/cloud/one/lib/remotes/vmm/kvm/kvmrc
/srv/cloud/one/var/remotes/vmm/kvm/kvmrc

However, when i change kvmrc file on KVM
file path is
/var/tmp/one/vmm/kvm/kvmrc.
I can't deploy VMs.
