[ovirt-users] about testing scenario

Hello , Everyone; My name is Leandro. I have been reading about virtualization features and Its benefits so Im thinking about deploying a virtualized IP core enviroment. Main services I will need to run are , dns , dhcp, radius , and openvpn. Since I have never installed ovirt , I would like to deploy a testing/learning scenario using two i5 with 6gb ram memory laptops. My idea is to run the ovirt engine in one machine and at least 3 virtual centos hosts in the other while I wait for the real servers. I have no plan of deploying any network storage. Some questions come to my mind: For the engine: Is there any recommended iso/distro with the ovirt package or should I use a machine with fedora/centos already installed ? For the node. Is there any recommended iso/distro? Where should I keep the iso file of the virtualized OS. (ex centos / routerOS.) Is it possible to deploy virtualized environment without network storage? I would like to run everything locally. My services requieres very fast i/o processing from the hard disk, My consern is that since I have 1gb network interface, the process can experience some delay or timeouts waiting data from the network. That is why I would like to keep the storage locally. I appreciate you help. Regards. Leandro.
