Re: [libvirt] [PATCH v4 3/3] virsh: Add support for text based polkit authentication

https://bugzilla.redhat.com/show_bug.cgi?id=872166 When the login session doesn't have an ssh -X type display agent in order for libvirtd to run the polkit session authentication, attempts to run 'virsh -c qemu:///system list' from an unauthorized user (or one that isn't part of the libvirt /etc/group) will fail with the following error from libvirtd: error: authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage' In order to handle the local authentication, we will use the new virPolkitAgentCreate API in order to create a text based authentication agent for our non readonly session to authenticate with. The new code will execute in a loop allowing 5 failures to authenticate before failing out. With this patch in place, the following occurs: $ virsh -c qemu:///system list ==== AUTHENTICATING FOR org.libvirt.unix.manage === System policy prevents management of local virtualized systems Authenticating as: Some User (SUser) Password: ==== AUTHENTICATION COMPLETE === Id Name State ---------------------------------------------------- 1 somedomain running $ Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- tools/virsh.c | 38 ++++++++++++++++++++++++++++++++++---- tools/virsh.h | 1 + 2 files changed, 35 insertions(+), 4 deletions(-)
