libvirt users - Oct 2015 - selective virsh host permissions

As a Systems Administrator, I would like to grant permissions to a certain
VM using unix groups. In this example there is a hypervisor with VMs
A,B,C,D and there is a group called fortadmins. The solution I am searching
forI would just allow fortadmins to use libvirt/virsh commands on VM D.

Does libvirt/virsh provide any way to easily accomplish this goal?

Jamie Ian Fargen

You can accomplish this using polkit

   http://libvirt.org/acl.html
   http://libvirt.org/aclpolkit.html

Please note, however, that you should not grant the ability to define XML
or otherwise make changes to the guest XML, as this privilege is effectively
equivalant to having root.

Giving users the ability to start/stop VMs is just fine. You can even
prevent users from seeing each other's VMs by restricting the
'getattr'
and 'read' privileges.

In current libvirt GIT there is a example file
'examples/polkit/libvirt-acl.rules'

Daniel

There are ACLs for that and libvirt has currently a polkit driver.  So
if you have and are using PolicyKit, you are only few steps away from
setting this whole thing up.  There are various links that might help
you with it:

  https://libvirt.org/acl.html
  https://libvirt.org/aclpolkit.html

Then there is an example rule file in our git tree that was recently
enhanced:

 
https://libvirt.org/git/?p=libvirt.git;a=blob_plain;f=examples/polkit/libvirt-acl.rules;hb=HEAD
