On a related note, it looks like the scope of Primary Storage has changed
in 4.2. What are the benefits of this scoping feature? For example, does
it help mainly if you want to migrate a VM from one cluster to another?
Thanks

Generally the targets I've worked with support different levels of
access control, so you may have a high level block where you can't

On revoke/grant access, If we're talking about individual volumes
being equal to a data/root disk, it's wise to adjust ACLs to only
allow access to the host that is currently wanting to run the VM/disk.
This way, cloudstack is authoritative in what's accessing the lun, and
you don't have to run a s
Hi,
I'm working on implementing a storage plug-in for CS 4.2.
I'm looking at the following Wiki page for guidance, but have some
