I’ve been trying to identify the source of the VM issues that I’ve been having, and I’m starting to believe it’s a hardware compatibility issue that I haven’t figured out how to address.
Recently built up a new system intended to be used as my daily driver:
Ryzen 9 5950x, 128G Ram, Nvidia Quadro M2000, freshly installed FC34
I did configure FC34 to use XFS instead of the default btrfs (primarily due to familiarity).
The first set of VM that I started to build out was a training VM that I have a static build process for. This training VM is to be used to provide tutorials for others, and has a well documented installation process (part of the training). This is a RHEL 7 VM, started on a RHEL 7.7 base, and upgraded to the latest version. The point of this is to say there should be no functional reason why this VM should not work/install correctly.
During the installation of the VM I for the first time ever saw a message along the lines of “This processor is not part of the Red Hat supported hardware list, please consult blah blah blah”. This of course was my first indication there was an issue. The system still worked reasonably well but seemed extremely slow. I increased the CPU/RAM on the VMs from 1CPU/4g to 2CPU/8G and finally to 4CPU/16G to try to resolve the issue.
I’ve been using virt-manager to configure/manage my VMs. I tried multiple CPU architectures for emulation purposes - qemu64, kvm64, host-passthrough, host-model. All options resulted in the same extreme sluggishness on any CPU intensive operation.
The configuration/deployment process for the application (Red Hat Certificate System) failed every time, no matter what architecture or CPU/RAM configuration I used.
I recently re-deployed the same configuration on an FC31 box using a 2CPU/4G ram setup - and the VMs and application deployed without any issues.
Assistance in isolating the configurations required to deploy RHEL 7 VMs with the given hardware configuration would be appreciated.
