While running a non-Windows guest such as Linux on Hyper-V, the Hyper-V management console may display messages similar to the one shown below:
Furthermore, upon examination of the Windows server event log, you may also observe messages in the format shown below:
The message text in the above images suggests that no Microsoft technical support will be provided until the integration services are upgraded.
The various messages shown in the symptoms section occur because the non-Windows guest integration services may not always have the code to interoperate with the latest Hyper-V protocols. This is due to the fact that Windows release cycles are not in sync with the release cycles of other operating systems. As a hypothetical example, the latest Red Hat Enterprise Linux (RHEL) release may ship in January but the latest Windows release may ship in the following September. Between January and September, the Windows team may upgrade the Hyper-V protocols due to which the RHEL release shipped in January may have integration components that were written based on earlier Hyper-V protocols. Now, when a user tries to run an older RHEL release as a virtual machine on a newer Windows release then they may observe messages suggesting that the RHEL integration components are degraded.
Users are hereby advised to ignore all messages and warnings that seem to indicate that no technical support will be provided because integration services for a non-Windows guest virtual machine are degraded. Microsoft will provide technical support even if when such messages are visible while running supported non-Windows guests on Hyper-V. Linux users may review a list of supported distributions on Hyper-V on the following page: Linux Virtual Machines on Hyper-V
Note that it is safe to ignore these messages because Hyper-V protocols are implemented to be backward compatible. Therefore, even if a certain non-Windows guest has integration services that were based off earlier Hyper-V protocols, the guest is expected to run flawlessly on newer Hyper-V releases.
