PfSense VM on ProxMox : Qemu-agent installation

weehooey

Hey @Bob-Dig I think it should. Of course, you will want to test to confirm.

Proxmox is KVM/QEMU under the hood. We have used this successfully with OpenStack (in OVHcloud), which is also KVM.

Although, if you have a VPS that is hosted by a third party, there may be things which prevent it from working correctly.

The QEMU guest agent gives insight into the VM and provides some communication. In Proxmox, with the guest agent, you get an accurate reading of the RAM the VM is actually using and the VM responds to the power off/reboot commands.

I would not want to run a VM without a guest agent for the platform it is running on.

@weehooey If I connect via VNC to it, it says QEMU, so I think I am good. But can't see any differences in their web-GUI nor in pfSense after installing.

does this work on 2.7.0?

It works the same on pfsense v2.6 and v2.7
You have to do all of

Create file /etc/rc.conf.local with above contents
Create file /usr/local/etc/rc.d/qemu-agent.sh with above contents and change it's properties to enable execute permission
Install the package qemu-guest-agent in the VM
Enable Qemu agent in Proxmox, stop the VM then restart it.

@Patch you do not need to stop and restart the VM.

Check out the script for the commands: https://github.com/Weehooey/pfSense-scripts

Neat, this works for 23.05.1 too.
Thanks

I am now a proxmox user too and your script is awesome, thanks.

Or do it manually.
Takes about 2 minutes using (paste from a cheat sheet works)

Diagnostics -> Edit file
Diagnostics -> Command prompt -> Execute Shell Command

Never failed and my preferred method, thanks Patch...

@weehooey

i was not able to use your script because the agent gives me a error.

service qemu-guest-agent start
Cannot 'start' qemu_guest_agent. Set qemu_guest_agent_enable to YES in /etc/rc.conf or use 'onestart' instead of 'start'.

but as soon as i added it in the /etc/rc.conf i was able to start the agent. Has something changed with 2.7.1? (first time using proxmox and QEMU)

@thewho I installed on 2.7 and upgraded to 2.7.1 and mine appears to remain functional. service qemu-guest-agent start tells me qemu_guest_agent already running? and provides the pid for it. That said .. something is wrong as my memory consumed in the proxmox host has doubled after the move 2.7>2.7.1 (3.2G>7.1G)
