“CPU Model ‘Host’ Requires Kvm or Hvf” | Fix

The CPU model we have chosen for the virtual machine (VM) is not compatible with the hypervisor we are using if we see the error message “CPU Model ‘Host’ Requires Kvm or Hvf” in the virtualization environment. The “host” CPU model is supported by two popular hypervisors: KVM and HVF. Make sure the hypervisor is compatible with the CPU model we selected.

We can experience performance issues or the VM may not function at all if the specifications of the hypervisor do not match the CPU model of the host. It is crucial that we choose the right CPU model based on which hypervisor it works with. In order to fix the error, we can try these steps:

1. Initially, choose a CPU model that works with the hypervisor, if at all possible.

2. Then, consider moving to a different hypervisor that is compatible with the preferred CPU model if the present hypervisor does not support the one we have selected.

3. The error message may sometimes suggest that the desired CPU model is not supported by the present hardware. The problem can be fixed by upgrading to a compatible piece of hardware.

4. Then, verify that the CPU model we want to use for the VM is supported by the CPU on the host system. Certain functionalities that are unavailable on earlier CPU models could be necessary for some CPU models.

5. Make sure that the virtualization software we use—such as VMware, QEMU, or VirtualBox—is up to date. Software updates can occasionally fix CPU model compatibility problems.

6. Check the system needs for both the guest OS we’re attempting to run and the virtualization software. Also, verify that the host system satisfies these specifications.
