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

[Ian Patton]

Hi,

I am wondering if there is a way to make sure that VMs of a certain type do
not get distributed all to the same host machine. For example, if you have
a few clustered VMs, for the sake of HA when there is a hardware failure,
you would want them distributed. Is this possible?

Thanks in advance,

Ian Patton

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

Dear Ian,

I forgot to mention that multicluster support [1] is an out-of-the-box
feature of OpenNebula 2.0.

Best,
