Question

Why AWS EC2 instance not detected correctly when we run lmvminfo.exe -long, getting UNKNOWNVM

--------------------
Virtual Machine Information
===========================
Hypervisor Detected: True
Running on Virtual Platform
FAMILY=UNKNOWNVM
NAME=UNKNOWNVM
UUID: ERROR - Unavailable.
GENID: ERROR - Unavailable.

Error: Failed to access virtual machine information

Answer

Try to check whatInstance Metadata Service (IMDS) version is used by the EC2 instance. If the ‘IMDSv2’ setting is configured in AWS then this is not currently supported by FlexNet Publisher instance detection so try to use ‘IMDSv1’ to detect the instance correctly.

NOTE: Our Engineering team is working on IMDSv2 currently and we will keep you updated. Also, read more about Use IMDSv2

Update On 31/Jan/2023:

AWS EC2 IMDSv2 detection capability has been added to FlexNet Publisher and is planned for release from FNP 11.19.3.0 (2023 R1).
