RE: Porting VMWare virtual setup into CloudStack
Hi
In our office we are having VMWare EsXi two Servers with multiple
VM's managed by VCenter. Can we manage Virtual Machines CloudStack by
installing it in one of the Virtual Machines.
Thanks in Advance
Best Regards

Instances yes. Overall cloud, that will take some time and energy, and a lot
of hacking, there was a proposal sometime back to import existing hosts and
instances to CloudStack which was never implemented, maybe in future.
Longer way: For each instances, export ova, deploy/start CloudStack, upload
ova and start instances in CloudStack.

I agree with Oliver, this is not a feature of cloudstack. Installs should start with green field hypervisors... Then migrate vm's in by way of template, into cloudstack.

It is most probably feasible to add a cluster managed by Cloudstack but not recommended or supported. Certainly I would not add an existing cluster as that could be asking for trouble. From my experience, it has issues with performance as Cloudstack talks via https to the vc api and is quite chatty and you may get undesired results, for example, Cloudstack not being able to manage VMs in virtual center correctly and even possible loss of data. We tried this in the early days of VMware integration with Cloudstack and the environment just did not work as expected. Tasks in VC just failed or never executed correctly.

Host management for vSphere is done through a combination of vCenter and the CloudStack admin UI. CloudStack requires that all hosts be in a CloudStack cluster, but the cluster may consist of a single host.

Hi Oliver
From you answer can I take its feasible to add current vCenter into
CloudStack but its not recommended. If so any particular reason.

I would set up a new virtual center and add this to Cloudstack and then one
by one export and import your VMs in to Cloudstack one by one. I would
definitely recommend not updating the database or importing your existing
virtual center in to cloudstack. The export format will need to be OVA. You
should not use the same virtual center that you manage with Cloudstack.
Importing them this way means Cloudstack will track the life cycle of the
VMs however the downside would be you will have a template for each VM you
import which will inevitably take up space on your secondary NFS server and
the ESX datastore. Depending on your size of VMs, depends on how long this
will take and you might have to tweak some global settings if the OVA
templates sizes are large.
It would be good if you could import them straight in but I do not think
this is possible.
Here is an extract from the installation guide.
6.4.2. Add Cluster: vSphere
Host management for vSphere is done through a combination of vCenter and the
CloudStack admin UI. CloudStack requires that all hosts be in a CloudStack
cluster, but the cluster may consist of a single host. As an administrator
you must decide if you would like to use clusters of one host or of multiple
hosts. Clusters of multiple hosts allow for features like live migration.
Clusters also require shared storage such as NFS or iSCSI.
For vSphere servers, we recommend creating the cluster of hosts in vCenter
and then adding the entire cluster to CloudStack. Follow these requirements:
Do not put more than 8 hosts in a vSphere cluster
Make sure the hypervisor hosts do not have any VMs already running
before you add them to CloudStack.
