#Hyper-V: #Linux Integration Services no longer function after a kernel upgrade

Consider the following scenario:

  • You are running Linux based virtual machines on Hyper-V with the 2.1 version of the Linux Integration Services installed.
  • You apply an updated kernel in the Linux based virtual machine.

After applying the kernel update, the Linux based guest operating system fails to boot with “Unable to mount root file system”.

This problem occurs because the Linux Integration Services must be recompiled after a kernel upgrade to function.

To prevent this issue, enable Dynamic Kernel Module Support (DKMS) before applying kernel updates.
