[one-users] guaranteeing the distribution of a certain group of VMs over multiple hosts

[Tino Vazquez]

Dear Ian,

There are several ways to achieve this.

Probably the most straightforward would be to split your hosts
machines in clusters (this can be easily achieved using a new probe
that tag the hosts as being, for instance, of type BLUE). Afterwards,
the VM templates can be filled with REQUIREMENTS expressions that will
drive them to one cluster or another.

Hope it helps,

-Tino
