Daniel summarized my approach nicely. Basically I'm looking at enabling multi-tenancy administration where several admins can exist but they can only see and/or manipulate with resources (VMs, storage, networks) assigned to them. By making use of a generic AC-module approach where actions gets passed through arbitrary complex access control can be enforced since the AC-module could implement/interface different schemes of granting/denying access depending on what enforcing policy wants to be used. One could for example use SELinux as a scheme to enable RBAC and/or tie it together with policies for sVirt.
An initial implementation step would be realizing the AC-module foundation and starting with moving out the RW/RO enforcement (currently residing within libvirt.c) as first basic enforcement scheme.

At this stage sVirt is primarily about protecting guests from each other, and protecting the host from guests. Konrad's suggestions are about protecting guests/hosts from administrators, by providing more fine grained control over what libvirt APIs an admin can invoke & on what objects. Both bits of work are required & are complementary to each other Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
