On the Proxmox host, stop the VM and add a virtual serial port:
bash
qm stop <VMID>
qm set <VMID> -serial0 socket
qm start <VMID>
In the FreeBSD VM, configure the serial console:
bash
sudo sysrc console="comconsole,vidconsole"
sudo sysrc boot_multicons="YES"
sudo sysrc boot_serial="YES"
sudo sysrc comconsole_speed="115200"
bash
qm stop <VMID>
qm set <VMID> -serial0 socket
qm start <VMID>
In the FreeBSD VM, configure the serial console:
bash
sudo sysrc console="comconsole,vidconsole"
sudo sysrc boot_multicons="YES"
sudo sysrc boot_serial="YES"
sudo sysrc comconsole_speed="115200"
