1> What is the proper order for VM creation for a Hyper-V  HA CSV environment; Create VM's on the drive then cluster it or create the Cluster then add VM's?  Does it really matter at all?
2> Until I get a second host machine, can I set up clustering on a single machine?

Hi Smantz,

I already answered to your other question about SQL and Hyper-V :)

1.) Order CSV / VM
I don't think there is any proper order... You can choose to migrate a VM VHD to a CSV after creating the VM. I still that if you're planning the implementation of a brand new virtual infrastructure (and your VM do not exist yet) then you should first create your CSV and then create your VM using the CSV space... You would then avoid to lose your time copying the VM to the CSV.
If you do have to copy your VM to the CSV then I suggest you to do so from the CSV owner. I think the CSV owner is also the CSV coordinator and it is the one that will handle the copy to the CSV: if you try to copy a VM from another node to the CSV then it will redirect the VM data to the other node (the CSV coordinator) which will transmit the data packet to the CSV.

2.) Setting up a cluster with a single machine
Clustering in 2008 has the clustering validation wizard: it allows you to check any problem with the cluster nodes prior to the cluster creation. You can create a single node cluster but you won't benefit from the cluster validation report. If you wait for the second node to be available then the validaiton report will show you any misconfiguration before creating the cluster... maybe better to wait.

Have a look at this article describing the creation of a cluster with Hyper-V.

Let me know if you have other question.

You always have flexibility, but there will be less reconfiguration involved if you setup the cluster first and then add the VMs. Otherwise you will need to migrate the VMs when you move them into the cluster. You can start with a single node cluster.

Hi Smantz,

Sorry I didn't see you answer earlier.
