To configure a CPU model:
- The correct CPU model should be configured for a KVM guest to mitigate Fatal glibc error: CPU does not support x86-64-v2. To view the bug, refer to Bug 2040657 - glibc: More Reliable CPU Compatibility Diagnostics.
To determine the current architecture level (on KVM guest or compute resource), the following cpu_check.awk script can be used:
To determine architecture levels inside the guest, run:
To check the architecture level on compute resource:
- ABI compatibility levels for CPU models, preferred CPU models for Intel x86, and AMD x86 compute resources are described at QEMU / KVM CPU model configuration.
To determine the CPU model on compute resource, run:
