Hi, OpenNebula will only monitor and manage VMs created through it, it will not interfere with your existing VMs.
But because OpenNebula assumes exclusive use of the hosts, the scheduler won't take into account the resources used by the previous VMs. You can however set manually how much host memory is reserved for the hypervisor and your VMs with the HYPERVISOR_MEM attribute in /etc/one/sched.conf [1].
