I have a virtual machine that is running on a KVM+QEMU stack with libvirt. The VM is using a qxl or virtio display and has a spice graphics listening on a port.
I'd like to change the password (in SPICE they call it "ticket") used to access that machine from virt-manager or remote-viewer while the machine is running. The old password should be invalidated immediately and new SPICE connections should only be possible with the new password.
