Still, this is IMO should be outside qemu, esp. as security is now much more than users/groups (i.e. selinux and friends).and concerned that we're loosening security for qemu non-users.IMHO this needs to hook into PolicyKit, since that is the access control framework that is being standardized on across the desktop. It is quite easy to work with - all you need do is provide a policy file, and to authorize a user, you'd run the 'pkcheck' program and its exit statusgives the result.
Absolutely. I wanted to not have a hard dependency on PolicyKit to start out with but that's always been the plan. I'd like to eventually add an optional PolicyKit dependency and when that's available not even bother with the qemu acl file. The nice thing about PolicyKit is the desktop integration. It's a much better user experience to allow a user to be prompted to allow qemu to access a bridge vs. having to error out to the user and tell them to muck with a config file.
