Unsupported Configuration Prompted by virt-manager

Symptom

When virt-manager is used, the following message is displayed:

libvirtError: unsupported configuration: ACPI requires UEFI on this architecture

Key Process and Cause Analysis

AArch64 KVM supports only UEFI BIOS. EDK2 is not installed when the source code is compiled. As a result, the firmware file cannot be identified.

Conclusion and Solution

1. Install EDK2.
   • CentOS 7.6

     yum -y install AAVMF

   • CentOS 8.1 or openEuler

     yum -y install edk2-aarch64

2. Restart the libvirtd service.

   systemctl restart libvirtd
