1.修改nova libvirt驱动的DEFAULT_UEFI_LOADER_PATH信息

文件路径：/usr/local/lib/python3.7/site-packages/nova/virt/libvirt/driver.py

原变量信息：

DEFAULT_UEFI_LOADER_PATH = {
    "x86_64": ['/usr/share/OVMF/OVMF_CODE.fd',
               '/usr/share/OVMF/OVMF_CODE.secboot.fd',
               '/usr/share/qemu/ovmf-x86_64-code.bin'],
    "aarch64": ['/usr/share/AAVMF/AAVMF_CODE.fd',
                '/usr/share/qemu/aavmf-aarch64-code.bin']
}

修改后:

DEFAULT_UEFI_LOADER_PATH = {
    "x86_64": ['/usr/share/OVMF/OVMF_CODE.fd',
               '/usr/share/OVMF/OVMF_CODE.secboot.fd',
               '/usr/share/qemu/ovmf-x86_64-code.bin'],
    #修改为麒麟操作系统启动uefi
    "aarch64": ['/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw']
}

2.修改qemu的nvram的配置

配置文件路径：/etc/libvirt/qemu.conf

#nvram增加aarch64的配置信息

nvram = ["/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw:/usr/share/edk2/aarch64/QEMU_VARS.fd","/usr/share/OVMF/OVMF_CODE.fd:/usr/share/OVMF/OVMF_VARS.fd"]

3./etc/nova/nova.conf 中，在libvirt模块下添加

hw_machine_type="aarch64=virt-4.1"

4.重启libvirtd和openstack-nova-compute的服务

systemctl restart libvirtd

systemctl restart openstack-nova-compute
