Federico, where exactly do you get this error? Would you attach the
setupNetwork log from supervdsmd.log?

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.
