Hyper-V Linux Integration Service for Ubuntu 18.04
Linux Integration Services. Linux Integration Services (LIS) is a package of drivers and services that enhance the performance of Linux-based virtual machines on Hyper-V. It enables features like:
- Graceful Shutdown
- Heartbeat to Hyper-V Manager
- Firewall Management IP Address Visibility
- Hot-add memory
According to the Microsoft documentation on Ubuntu virtual machines, they state that Linux Integration Service is built into the OS. However this is not the case. So in order to make use of the benefits of LIS, you need to perform some manual steps.
