What is a prerequisite for using the savevm and loadvm monitor commands to manage snapshots?

The VM must be paused before taking a snapshot

The VM must be using VirtIO storage drivers

The disk image must be in qcow2 format

The QEMU Guest Agent must be installed

Which QEMU command-line option is required to enable communication with the QEMU Guest Agent?

-chardev socket,path=/tmp/qga.sock,server=on,wait=off -device virtio-serial -device virtserialport,chardev=qga0,name=org.qemu.guest_agent.0

-drive file=disk.img,format=qcow2

An administrator created a snapshot of a QEMU VM using the monitor command savevm before a software update. The update failed, and the administrator wants to revert the VM to the pre-update state. Which sequence of monitor commands should be used?
