pfSense with Ubuntu 18.10 and XEN 4.9.2

[volkerg]

I want to share some hints i have found out with Installation PfSense on Ubuntu 18.10 and XEN 4.9.
Following Configuration is running best with german VDSL 250MBit.
Physical NIC is a Intel e1000e 4-Port Gbit Card where i use two of them as xenbr0 and xenbr1
i have to use the virtio Drivers, that is only possible with tho following configuration

in the xl.cfg file for virtual machine (hvm):
'model=virtio-net' in the VIF definition

on the pfsense (after first boot)
parameter in /boot/defaults/loader.conf
hw.xen.disable_pv_nics=1

check Disable hardware checksum offload under System > Advanced on the Networking tab

that is for me the "one and only" Configuration

right now i am getting full speed (>30MByte per Second) with my virtualized pfsense.
i have to insert the parameter in the loader.conf after every update, because it is gone.
Before i used em PV Nics (em0 and em1). But i realized high CPU and only 13 MByte/s with my new VDSL Connect.

i had a lot of pain to find out all that stuff, so i want to share my expirience
regards

forget that i don't want to use the xen drivers (xn0 and xn1) because there is no VLAN tagging possible.

removed the parameter from /boot/defaults/loader.conf and put it in

/boot/loader.conf.local

upgrade from 2.4.3 to 2.4.2_2 worked fine, parameter (and NICS) are still there
