The real benefit of the of using a separate zvol for each vm is the 
instantaneous cloning of a machine, and the clone will take almost no 
additional space initially. In our case we build a template VM and then 
provision our development machines from this. 
However the limit of 32 nfs mounts per esx machine is kind of a bummer.

Why the use of zvols, why not just;

zfs create my_pool/group1
zfs create my_pool/group1/vm1
zfs create my_pool/group1/vm2

and export my_pool/group1

If you don't want the people in group1 to see vm2 anymore just zfs rename it to 
a different group. 

I'll admit I am coming into this green - but if you're not doing iscsi, why 
zvols?
