[ovirt-users] Advise needed: building cheap HA oVirt cluster with just 2 physical servers

[Artem Tambovskiy]

Thanks for an article, Martin!
Any chance to configure a third cost to act as GlusterFS Arbitr only using
this wizard?

And stupid question - how to make this wizard up and running? I've
everything installed and nothing is runnin on port 9090 :)

Regards,
Artem
