Comment 1 Itamar Heim 2012-10-24 02:16:59 UTC

storage admin is allowed to manage storage domains, and disks. not VMs.
attaching/removing disks from VMs requires more permissions.
I don't see this as a bug.

Comment 2 Ondra Machacek 2012-10-24 11:17:39 UTC

So the backend shouldn't return that it can:

for r in API.roles.list():
    if r.get_name() == 'StorageAdmin':
        print 'attach_disk' in [p.get_name() for p in r.get_permits().list()]

>>> True

That's true as well.
You need two permissions in order to attach a disk to a VM:
1. Permissions on the disk, that allows you to attach it - "ATTACH_DISK" on the disk.
2. Permissions on the VM, that allows you to configure storage for it - "CONFIGURE_VM_STORAGE".
