Does this happen on the XEN Server of Client (guest OS). 
If Xen, which xen version? 

I notice on XCP-ng 7.6 that, somehow the management IP changed from static to dhcp. 
In 7.6, im prepaired an upgrade to 8.0, which should be done somewhere this week. 
Fix for this is very simple, goto the xconsole and set the ip again. 
( no reboots needed )

If you talking about the VM. 
AND is has only one ip configed by default. 

You should be able to run this. 

https://raw.githubusercontent.com/thctlo/debian-scripts/master/setup-systemd-networkd.sh 
It does not change anything to the system, but i give you the option to switch to systemd. 
Currently all my domain members are configured throught systemd-networkd because is safe packages to install.
