8-host limitation comes from the limitation posted from VMFSv3 for
linked-clone usage. So in CloudStack, it is an artificial limit we post to
reduce possible runtime problems.
We have a default setup about this limitation in Config.java, the last
section (shown as "1-8") gives a validation range, any change from UI will
go through our java validator, so it may prevent you from changing to any
number that is greater than 8.
VmwarePerClusterHostMax("Advanced", ManagementServer.class, Integer.class,
"vmware.percluster.host.max", "8", "maxmium hosts per vCenter cluster(do
not let it grow over 8)", "1-8"),
If you are running vCenter/ESX 5.1 and up, you are safe to increase
cluster size to 16, to workaround the hard-coded 1-8 range in java
validator, you may directly make a change in database.
I think raising cluster size limit will be addressed soon in upcoming
CloudStack releases.
