The behavior of the Oracle VM Server host is undefined if used in an environment where your IP address may change due to DHCP lease expiry.

E.3 Guest Console Access

You can connect to a guest’s console using Oracle VM Manager. If you do not have access to Oracle VM Manager, you can configure access to a guest’s console with VNC (Virtual Network Computing). VNC access to guests requires that VNC access is
