If you have a visualized instance of pfSense, you may want to install the qemu-guest-agent package to allow tighter integration between the pfSense Client and the Host systems. (I use Proxmox VE)
From the pfSense CLI
pkg install qemu-guest-agent
Enable the service
sysrc qemu_guest_agent_enable="YES"
From the WebUI, install the package ‘ShellCMD’ then create a new command entry. This command will start the Guest Agent at the end of the boot sequence.
