Update:

It's been a few days, but I did (finally) enable the virtualization in the BIOS.

Unfortunately, I have the exact same symptom.

My Ovirt version is  Version 4.4.4.7-1.el8

lscpu shows the vmx, vnmi, and tpr_shadow flags are set.

I did find this tidbit: https://www.mail-archive.com/users@ovirt.org/msg64312.html

The Xeon E5-2680 v3 appears to be a "Sandy Bridge-EP" based processor, so I'm not really clear about why ovirt is looking for the model_Cascadelake-Server-noTSX flag 

The <model usable="yes"/> elements displayed by virsh domcapabilities show SandyBridge-IBRS and SandyBridge, but not SandyBridge-EP.

I did see references to KVM specific bios enablements, but nothing usable for identifying them in the BIOS settings.

Any ideas would be appreciated

Thanks again in advance

Intel virtualization (VT-x)
Previously codenamed "Vanderpool", VT-x represents Intel's technology for virtualization on the x86 platform. On November 13, 2005, Intel released two models of Pentium 4 (Model 662 and 672) as the first Intel processors to support VT-x. The CPU flag for VT-x capability is "vmx";


So you need to enable the virtualization for your system. For details check your hardware vendor's documentation.

Next question ... how do I enable the vmx flag?  

My google-fu is failing me here. I find a lot about how to see if its set, but nothing about how to do it.

Thanks,
David Johnson
