I’m using the option
services.qemuGuest.enable = true in my config and I can see the
qemu-ga service is running correctly. Now, when I try resetting the root password from the Hetzner Cloud dashboard, which uses the qemu guest agent, I get a “server password reset has failed” (but I get a “info: guest-ping called” in the qemu guest logs).
However if I stop the service, run
qemu-ga manually (as root) and try the “reset root password” feature in the dashboard, it works.
Any idea what’s going on? Could it be related to the way systemd runs the service?
