QEMU Guest Agent install problems on pfsense in VM

[Arbadacarba]

I have a couple of Hypervisors with pfsense running on them (Unraid and Proxmox) and finally figured out a problem I'm having is caued by pfsense not shutting down when asked.

 

So I installed the QEMU Guest Agent on the Proxmox VM and it seems to have worked beautifully.

So lets try the pfsense VM on the Unraid server:

1660578057.841196: critical: failed to initialize guest agent channel

 

OK, I'm clearly missing something... How do I get Unraid to open that channel?

 

from the xml:

 

    <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-37-pfSense - Cerberus/org.qemu.guest_agent.0'/>
      <target type='virtio' name='org.qemu.guest_agent.0' state='disconnected'/>
      <alias name='channel0'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>

 

 

(To be fair the first install is on pfsense CE and the Unraid one is running pfsense plus... So that could be the cause but I don't think so.

 

Thanks for any input

Yes same error for me on unraid, it was working on proxmox. The interesting thing is that soft off is working..

[Arbadacarba]

I'm wondering if something changed with the pfsense build, because I would swear that the system was not performing the soft shutdown.

 

I built a test vm last night and it does now perform the shutdown as desired. So maybe I don't really need the Guest Agent with pfsense.

 

I'm still curious as to why it fails though.

I got it running and see the NICs now in the unraid-console.
But I had to start it manually, starting the service automatically is not working (using the same link as @Arbadacarba).

 

there is not even a logfile in /var/...

Did anyone find a solution?

Found a solution in the meantime:

 

pkg install -y qemu-guest-agent

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

cat > /usr/local/etc/rc.d/qemu-agent.sh << EOF

#!/bin/sh

sleep 5

service qemu-guest-agent start

EOF

chmod +x /usr/local/etc/rc.d/qemu-agent.sh

service qemu-guest-agent start
