(should work for most distributions) or reboot the guest.įirst you have to download the virtio-win driver iso (see Windows VirtIO Drivers).
Then enable the service to autostart (permanently) if not auto started, with On Debian/Ubuntu based systems (with apt-get) run:ĭepending on the distribution, the guest agent might not start automatically after the installation. We show here the commands for Debian/Ubuntu and Redhat based systems: On Linux you have to simply install the qemu-guest-agent, please refer to the documentation of your system. Or via CLI: qm set VMID -agent 1 Guest Linux You have to install guest-agent in each VM and then enable it, you can do that in the Proxmox VE Webinterface (GUI) 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).If the guest agent is enabled and running, it calls guest-fsfreeze-freeze and guest-fsfreeze-thaw to improve consistency. To freeze the guest file system when making a backup/snapshot (on windows, use the volume shadow copy service VSS).To properly shutdown the guest, instead of relying on ACPI commands or windows policies.In Proxmox VE, the qemu-guest-agent is used for mainly three things: To exchange information between the host and guest, and to execute command in the guest. The qemu-guest-agent is a helper daemon, which is installed in the guest. 2.3 Testing that the communication with the guest agent is working.
