XL create says it parsed the .cfg file succesfully but for some reason it doesn't actually change anything in...

Currently I am trying to duplicate a VM with Xen. Duplicating the VM is working fine. However, I can not manage to dynamically change the IP-address and hostname of the VM.
First the steps that I followed:
* I shutdown the VM (xl shutdown Ubuntu16.04)
* Next I created a new LVM in VolumeGroupXen and copied the LVM of the VM I want to duplicate inside.
sudo lvcreate -L5120 -s -n '/dev/VolumeGroupXen/Webserver2-disk' /dev/VolumeGroupXen/Ubuntu16.041-disk
sudo lvcreate -L5120 -s -n '/dev/VolumeGroupXen/Webserver2-swap' /dev/VolumeGroupXen/Ubuntu16.041-swap
Next I copied the original config file (Ubuntu16.04.cfg) to Ubuntu16.041.cfg
With the following input:
:/etc/xen$ cat Ubuntu16.041.cfg
#
# Configuration file for the Xen instance Ubuntu16.04, created
# by xen-tools 4.7 on Thu Nov 22 16:40:28 2018.
#
#
# Kernel + memory size
#
bootloader = '/usr/lib/xen-4.9/bin/pygrub'
vcpus = '2'
memory = '1024'
#
# Disk device(s).
#
root = '/dev/xvda2 ro'
disk = [
'phy:/dev/VolumeGroupXen/Ubuntu16.041-disk,xvda2,w',
'phy:/dev/VolumeGroupXen/Ubuntu16.041-swap,xvda1,w',
]
#
# Physical volumes
#
#
# Hostname
#
name = 'Ubuntu16.041'
#
# Networking
#
vif = [ 'ip=xxx.xxx.xxx.121 ,mac=00:16:3E:C1:55:39,bridge=xenbr0' ]
#
# Behaviour
#
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
As you can see I adjusted the disks to the correct path (which works fine) and I adjusted the IP and hostname. However, both the IP and hostname stay the same (as the original VM) after booting the VM with xl create Ubuntu16.041.
Does anyone know what I am doing wrong? Or is it simply not possible to update the IP address and hostname like this?
