Dear list members,

how important is the homogenity of a kvm cluster?

The docs are very strict here:
- All hosts within a cluster must be homogenous. 
  The CPUs must be of the same type, count, and feature flags.
http://docs.cloudstack.apache.org/en/latest/installguide/hypervisor/kvm.html#system-requirements-for-kvm-hypervisor-hosts

What happens if I integrate different nodes into one cluster as I know
I don't want to do live migration and use them for different workloads?

Would it be possible to tag the differing hosts (e.g. test/prod) so
they don't get mixed or would it really be needed to create a seperate cluster
for that?

N.B.: I also opened a pull request that is influenced by this:
https://github.com/apache/cloudstack-documentation/pull/48
(in short: if all host MUST be homogenous, what sense makes setting CPU 
features?)

Bye
Michael
