I am installing Red Hat Linux 6.9 as a VM in Hyper-V on an HP laptop running Windows 10. After the install completes and the VM reboots, it gives me the message, "Detected CPU Family 6 model 142; Warning: Intel CPU model - this hardware has not undergone testing by Red Hat and might not be certified" (see screenshot). I also got this message when installing Red Hat Linux 6.7, but Linux booted up fine after getting that message. Now, with 6.9, after I get that message, I get a black screen with a funny looking bar across the top of it and then it just hangs (see screenshot). Anyone else experienced this issue or does anyone have any suggestions?
Sounds like it is more of a Hyper-V problem than a Red-Hat issue.
It may well be that Hyper-V didn't support newer technology that
Red-Hat may have implemented at the time.
When running any guest OS through a hypervisor, you should try
the hypervisor forums first. This isn't a Windows 10 forum.
