I use Proxmox for my hypervsior and recently installed pfSense as a firewall. I use the QEMU Guest Agent to get more detailed info about the VM's that are running in the Proxmox console.
This post shows the process to get the QEMU Guest Agent running on a pfSense firewall.
The following software versions were used in this post.
Install the qemu-guest-agent package.
pkg install -y qemu-guest-agent
Once installed, there is a note on how to setup the agent.
======================================================= Modify your `/etc/rc.conf` by adding these settings qemu_guest_agent_enable="YES" qemu_guest_agent_flags="-d -v -l /var/log/qemu-ga.log" and run # service qemu-guest-agent start For detailed help use `qemu-ga -h` =======================================================
I am following the steps in the script here (with slight modifications).
Append to the /etc/rc.conf.local file.
cat >> /etc/rc.conf.local << EOF qemu_guest_agent_enable="YES" qemu_guest_agent_flags="-d -v -l /var/log/qemu-ga.log" #virtio_console_load="YES" EOF
Create the /usr/local/etc/rc.d/qemu-agent.sh file.
cat > /usr/local/etc/rc.d/qemu-agent.sh << EOF #!/bin/sh sleep 3 service qemu-guest-agent start EOF
Make the /usr/local/etc/rc.d/qemu-agent.sh file executable.
chmod +x /usr/local/etc/rc.d/qemu-agent.sh
Start the QEMU Guest Agent service.
service qemu-guest-agent start
Confirm the QEMU Guest Agent service is running.
service qemu-guest-agent status # Output qemu_guest_agent is running as pid 85066.
If you have not done so already, you need to enable the guest agent of the VM in Proxmox. Navigate to:
If you just enabled the QEMU Guest Agent, the final step is the reboot the VM. This is required to get the QEMU Guest Agent working with Proxmox.
Confirm that the VM's IP address information is available in the Proxmox console by browsing to:
In this post I showed you how to configure the QEMU Guest Agent on a pfSense firewall for use on a Proxmox hypervisor.
