[nova][glance] Instance Password Reset

Hi, I am trying to enable guest password reset for windows and linux guests. Is it possible to do it when the instance is running ? I am using wallaby release. By searching, I have found that qemu-guest-agent is required to reset the password. But I didn't see the the image property for it. https://opendev.org/openstack/glance/src/branch/stable/wallaby/doc/source/ad... On other link I have found hw_qemu_guest_agent property for image this will help in this but looks too old and seems to be deprepacted. https://wiki.openstack.org/wiki/VirtDriverImageProperties My objective is to reset the linux and windows guest password or inject new key pair. Need your help, how to achieve it. - Ammad
