Clustering multiple VM's

We're currently using Hyper-V with Windows Failover Clustering. Since our
SAN has a limit of 32 on the number of LUN's supported we'de like to combine
a number of virtual machines into a single failover application so they can
share the same LUN.
Is there any way to add another virtual machine to an existing virtual
machine cluster application?
I guess we could do it manually but the content of the 'VmSwitchPorts'
private property of the virtual machine configuration isn't very clear to
me. Is there any documentation on how to manually create that property?

This is what you are after:
http://support.microsoft.com/?id=951308

Allow for more than one virtual machine in a "Services or Applications"
group: This is one of the important updates, we will now let you add/select
multiple virtual machines in High Availability (HA)wizard. The wizard will
detect if there are multiple VM's that have files on the same clustered
disk. If it is the case they will be enabled and configured for HA

However, do understand that if 1 machine within the Cluster Applicaction
group fails all virtual machines with move to the other node.

Hope this helps!

Thanks a lot for the information. I'll try this update. It seems to solve
most of the issues I have with Hyper-V in cluster.

Rememeber that if 1 VM inside the cluster (Application/services) group
fails, all other VMs on that same LUN will failover.
For more flexibility, look at third part offerings that provide a cluster
filesystem (providing simultaneous read/write access from # nodes in the
cluster) like SANbolic KayoFS (for HyperV only) or MelioFS (Enterprise
level, many # scenarios).

Hope this helps!
