====== Proxmox - Guests (VMs and Containers) - Qemu-guest-agent ====== The **qemu-guest-agent** is a helper daemon, which is installed in the guest. * It is used to exchange information between the host and guest, and to execute command in the guest. The qemu-guest-agent is used for mainly three things: * To properly shutdown the guest, instead of relying on ACPI commands or windows policies. * To freeze the guest file system when making a backup/snapshot (on windows, use the volume shadow copy service VSS). * If the guest agent is enabled and running, it calls guest-fsfreeze-freeze and guest-fsfreeze-thaw to improve consistency. * In the phase when the guest (VM) is resumed after pause (for example after shapshot) it immediately synchronizes its time with the hypervisor using qemu-guest-agent (as first step). ---- [[Proxmox:Guests (VMs and Containers):Qemu-guest-agent:Install Qemu-guest-agent|Install Qemu-guest-agent]] ---- ===== References ===== https://pve.proxmox.com/wiki/Qemu-guest-agent
