I have 2 hosts per cluster, and i have 2 clusters, 4 hosts (its an Huawei x6000)

I know oVirt don't support disperse, that's why i run gluster outside of oVirt.
And doing that i get a bit more freedom with setting up gluster.
So what would be an good setup to be able to use as much space as possible and some redundancy with the 4 hosts i have?

I did not quite get this - are you saying you can have only 2 nodes in
one cluster?

Disperse volumes are not supported with oVirt. It's either replica 3
or replica 2 + arbiter.
