Qemu-Guest-Agent is a helper daemon that is installed on the guest system. It is used to exchange information between the host system and the guest, allowing some commands to be executed on the guest system. Commonly used commands include:
- shutdown/reboot the guest system without relying on ACPI commands or Windows policies
- changing the password of the root user
- re-installation guest OS
- freezing the guest system before starting the backup. This will provide an opportunity to get a full backup copy, especially if there are databases in the guest system. Learn more about how it can be implemented here
- adding/replacing IP address for Windows
