Adding CloudStack to existing Xenserver 6.2 pool
Hi
We have an existing Xenserver 6.2 pool with more than 100 VMs and several
hosts.
We are using NFS for all storage and we match all requirements in term of
networking for cloudstack installation.
my question is it safe to install cloudstack on the existing pool ? or that
will affect the existing VMs and or hosts ?
I am ok with migrating all existing VMs to cloudstack or even not migrating
them.
my only concern is that If cloudstack can co exist with VMs thats are
existing in the system and if not if there an easy way to make existing VMs
managed by cloudstack
thanks

I have the same problem, I want to convert infrastructure to cloud environment, but can't be done just like that. In my case I can't even effort my self downtime of VM-s and migrate it to cloud suing templates.
So can anyone from Cloudstack give us king of instructions, method how to do that.

Posted by Geoff Higginbottom <ge...@shapeblue.com>.
Host by Host migration is the way to go, but definitely use a new NFS share and not the original one.
One more word or warning, try to keep the amount of time you have a three Host cluster to a minimum as this can result in an unstable Pool if the Pool Master goes offline.

What I will do is that
1- I will eject one host from exisiting pool (the hosts are already under
commited)
2- setup cloudstack on the ejected host
3- will start adding vms to the new cloudstack cluster one by one

Moftah,
Do NOT try to add this pool to CloudStack, you could lose all your existing VMs.
What you need to do is setup a new pool (CloudStack Cluster) then import each VM into CloudStack.
