Customers have reported that they have noticed RedHat clients hosted in Hyper-V are not properly showing the Resource Type.
Windows clients hosted on the same Hyper-V host are properly identified as Virtual Machines.
ITMS 8.6 RU1 and RU2
Known issue. Hyper-V was not supported until ITMS 8.6 RU3 which is why the machines were reported as a physical resource.
ITMS 8.6 RU3 addressed this issue and support for Hyper-V virtualization detection was added.
After upgrading to ITMS 8.6 RU3, it should display the proper Resource Type as a Virtual Machine.
