[ovirt-users] Testing openstack inside ovirt environment

Hello, Up to now I only tested openstack on physical hw. I would like to make some tests in a virtual environment. Not considering at the moment cinder and glance integrations provided by oVirt but full openstack itself. Are nestedvt and macspoof vdsm hooks the only requirement I should care about to be able to go? Also, supposing I go with a preliminar pre-test of openstack in virtual environment using plain qemu/kvm with virt-manager, it's clear to me how to enable the nested kvm for the host, but what should be the commands to give on host side so that the openstack instances will be able to communicate with the outside world (the commands that in ovirt I presume are run by the macspoof vdsm hook). Thanks in advance, Gianluca
