There seems to be some misunderstanding here.

dhcpd services for a vm are provided by the host running the vm. 
Depending on the vm software e.g. KVM/QEMU or VMWare Workstation there 
will be different mechanisms to configure or disable this service to the 
vm client.

However it is not necessary if you configure the vm client using the 
systemd networking client service - as the OP has done.

More relevant is explicitly disabling any competing network clients on 
the vm that may affect things like DNS.

I recommend :

sudo systemctl disable NetworkManager.service
sudo systemctl stop NetworkManager.service
sudo systemctl mask NetworkManager.service

sudo systemctl disable systemd-networkd
sudo systemctl stop systemd-networkd
sudo systemctl mask systemd-networkd

I reiterate that if DNS resolution is needed it needs to be set in 
/etc/hosts and/or in /etc/resolv.conf

(I also use systemd-networkd in preference to the other two types of 
client networking)
