However, don't you think it breaks the concept of a "Zone" being a "Data
Center"?
To me, one could/should be able to run clusters with different
hypervisors within the same pod.
I might just be a little too picky on terms tho :P

While you can do it as both Francois and Geoff have said. I can tell you
that our "Best Practice" that we implement with is that they be separate
zones to avoid as many of problems and complex configurations as possible.

Just to confirm, you can create a Cloud with a single Zone, containing
both XenServer Clusters and VMware Clusters, but you should create
unique PODs, one for XenServer and one for VMware
This should be documented :P (or maybe it is)
Because XenServer uses LinkLocal and VMware does not, the Reserved IP
Ranges for each POD will be significantly different.
Regarding System VMs, there is a Global Setting which allow you to
control which Hypervisor the System VMs will prefer, its
'system.vm.default.hypervisor' if you do not set this, it typically
creates them on the first available Cluster, then sticks with that
Hypervisor type.
Changing that global setting, restarting the management service, then
destroying the system VMs will see them move from one type of hypervisor
to another, I have done this many time, so if it's not working, you have
a problem somewhere.
That explains couple issues I had with the VRs. They were constantly
trying to launch on the last added cluster (in my case VMWare).
Thanks for the precisions Geoff!

Subject: Re: XenServer and VMWare Cluster, same Zone/Pod
this is odd indeed, have you tried these actions against homogenous
clouds?
I wonder that to see if this can be reproduced to see if its an
environmental issue vs mixed cloud bug.

Ok, so restarting the management service resolve a part of it.
Templates are now available and on the filesystem.
Now I am facing another issue, I cannot deploy a VM from any template

Hi,
Just a quick question, is there any issues that we might face if we
have a XenServer Cluster and a VMWare Cluster in the same pod/zone?
Will CloudStack spin 1 SystemVM for each hypervisor?
I am seeing that the system vm template for vSphere says "download
complete", but without any size in the UI/Database. The default
template for vSphere will not download as well. We are on CS 4.0.1
