Thanks Karli! Though it SHOULD be possible to start with eth0 and eth0.2 on the host (where "2" is the vlan id of your manamgement network), and from there on, do all configuration via Engine. I'd like to automate as much as possible out of this process, and iron out remaining bugs. Hence, I would like to hear more about Federico's mode of failure.

One comment to your wiki page: in order to better intergrate with our recent source-routing support (mostly useful for display network), please set GATEWAY only in ifcfg-ovirtmgmt, and remember to set DEFROUTE=no in any other ifcfg that mentions IPADDR so as not to override the default. Dan.
