[one-users] Wrong IP Address

[Guba Sándor]

Opennebula calculate IP address from MAC address and it's show that IP 
address as leased. However the DHCP server is running by libvirt and it 
has no idea that it's need to assign IP by mac address so it's assign IP 
by other metric. You can generate host file with proper mac-ip pairs or 
contextualize vm-s or somebody know other way to keep it synchronized.
