Hello!
According to the documentation access control
drivers are not in really "good condition". There is a polkit, but it
can distinguish users only according the pid. However, I have met some
articles about more fine-grained control and about selinux drivers for
libvirt? So, what is the status now? Should I implement something by
myself if I want access based on login, are their instructions how to
write these drivers or there is smth already?
