When I bring up
libvirt-manager from the usual menu and try to connect to QEMU/KVM, I get the following not so informative error messages:
Unable to connect to libvirt qemu:/// system
authentication failed: access denied by policy
This just started happening. Heretofore, I was prompted to enter the root password. So the question is: What policy and how do I change it?
If I launch virt-manager from the terminal using
sudo (which I’ve never had to do before), things work normally (except, of course, I’m not prompted to enter a password when connecting).
