If youre running Debian KVM's, i would also recommend using the "cloud" linux kernel from backports (or actual buster). Google Cloud is KVM, so all its optimizations should be of benefit.

https://packages.debian.org/stretch-backports/linux-image-cloud-amd64

Not sure what optimizations Google makes but because I'm cowboy (and because snapshots) I installed the cloud package. I'd really like to know what optimizations they made so I could compare metrics against an untuned machine.

For simple folk like me here's the process:

# Add backports to sources.list:

nano /etc/apt/sources/list
#Stretch Backports
deb http://ftp.debian.org/debian stretch-backports main contrib main
deb-src http://ftp.debian.org/debian stretch-backports main contrib main

# Update the sources

apt update

# Install the cloud package

apt install linux-image-cloud-amd64

FYI this also installs apparmor.

Uname -a :

4.19.0-0.bpo.5-cloud-amd64 #1 SMP Debian 4.19.37-3~bpo9+1 (2019-05-18) x86_64 GNU/Linux

This along with other tunables could probably be made into a scipt but I'm still not sure what the ROI will be yet.
