Does the setting for offline actions have to be changed for each machine in the evironment separtely, or is there a way to do this for a set of computers at one shot?

I'm following with interest the improvement of Hyperv but sadly I've to admit I'm a little disappointed by the lack of integration between Hyper-V and clustering service.

If it has to compete , seriously , with vmware'esx ( now vsphere ) much improvements should be made.

Firstly taking down a HA VM from Hyperv console or SCVVM should "trigger" something in cluster service which prevent it from restarting the VM ( as it would in a real failure case )

It should not be accepted manual intervention int "option tab" of the clustered resource.

Second the snapshot feature is long behind the vmware counterpart. Is it acceptable that VM has to be taken down "only" to delete a snapshot ? I realy think is not

As far as I know such problems still apply on upcoming R2

Best regards

This way works, but if you choose shutdown within the cluster administrator, not Hyper-V manager or within the VM itself, the VM will stay shutdown allowing the merge to happen. Also, if you use SCVMM and choose shutdown from the SCVMM console, the VM will also stay shutdown even in a clustered config. This will also allow the merge to happen.
