Cluster level OS Preference

[Mārtiņš Jakubovičs]

Hello,

Is this possible to create cluster level OS preference (same as host's 
OS preference)? I would be happy to create two different clusters, one 
for windows, and second for linux instances.
Right now, if I have two clusters and in one all hosts have same OS 
preference (for example - Windows), CentOS machines starts on that 
cluster anyway, and windows machines start on second cluster, which have 
CentOS OS preference.

Is there any workaround?

Best regards,
Martins
