kvm command line tool virsh when access remotely will ask for authentication , which is quite annoying at times to fix this we can add a polkit rule to allow users to access libvirt daemon
==== AUTHENTICATING FOR org.libvirt.unix.manage ===
System policy prevents management of local virtualized systems
Authenticating as: cipher
Password:
==== AUTHENTICATION COMPLETE ===
Id Name State
—————————————————-
1.create a file called 80-libvirt-manage.rules at /etc/polkit-1/rules.d/
#cd /etc/polkit-1/rules.d/
#ll
-rw-r--r--. 1 root root 974 Aug 4 2017 49-polkit-pkla-compat.rules
-rw-r--r--. 1 root root 326 Jan 15 2014 50-default.rules
#touch 80-libvirt-manage.rules
add below code to the file
polkit.addRule(function(action, subject) {
if (action.id == "org.libvirt.unix.manage" && subject.local && subject.active && subject.isInGroup("wheel")) {
return polkit.Result.YES;
}
});
#save and restart polkitd daemon
2.Add user to libvirt group
# usermod -aG libvirt cipher #newgrp libvirt
Now we can access libvirt without authentication.
