Subject RE: Externally Managed Clusters - pointer to more info?
Date Thu, 19 Jul 2012 21:51:24 GMT
Hi Chiradeep:

So, it sounds like there isn't a way in the same cluster for two 
XenServer hosts to not pool CPU, memory, and ip addresses?

To get that kind of cpu, memory and ip address management separation, 
it sounds like each host should be in a different cluster. Right?

AFAIK, this is available only for VMWare clusters currently. The main difference is that vCenter
takes care of HA and you can live migrate using vCenter and CloudStack will cope with the
out-of-band change.
