安装qemu、libvirt

yum install libvirt libvirt-client -y
yum install qemu -y

安装固件包

yum install edk2-aarch64

固件文件

配置/etc/libvirt/libvirtd.conf 

auth_tcp = "sasl"
listen_tcp = 1
listen_tls = 0
tcp_port = "16509"
unix_sock_dir = "/run/libvirt"

配置/etc/libvirt/qemu.conf

nvram = ["/usr/share/edk2/aarch64/QEMU_EFI.fd:/usr/share/edk2/aarch64/QEMU_VARS.fd","/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw:/usr/share/edk2/aarch64/vars-template-pflash.raw"
]

启动服务

systemctl enable libvirtd --now
systemctl enable libvirt-guests --now

其中libvirt-client提供了virsh指令

管理已存在的qemu虚拟机

创建配置

<domain type='kvm'>  //如果是Xen，则type=‘xen’<name>redflag1</name> //虚拟机名称，同一物理机唯一<uuid>44748c15-7c00-4817-8724-675a27c3f821</uuid>  //同一物理机唯一，可用uuidgen生成<memory>67108864</memory><currentMemory>67108864</currentMemory>  //memory这两个值最好设成一样<vcpu>64</vcpu>  <cpu mode="host-passthrough"/><os><type arch='aarch64' machine='virt'>hvm</type> //arch指出系统架构类型，machine 则是机器类型，查看机器类型：qemu-system-x86_64 -M ?<boot dev='hd'/>  //启动介质，第一次需要装系统可以选择cdrom光盘启动<bootmenu enable='yes'/>  //表示启动按F12进入启动菜单</os>  <clock offset='localtime'/>  //虚拟机时钟设置，这里表示本地本机时间<on_poweroff>destroy</on_poweroff>  //突发事件动作<on_reboot>restart</on_reboot><on_crash>restart</on_crash><devices>   //设备配置<emulator>/usr/bin/qemu-kvm</emulator> //如果是Xen则是/usr/lib/xen/binqemu-dm<disk type='file' device='disk'> //硬盘<driver name='qemu' type='qcow2'/><source file='/home/yeqiang/qemu-virtual-machine/redflag.qcow2'/><target dev='vda' bus='virtio'/><address type='pci' domain='0x0000' bus='0x00' slot='0x00' function='0x0'/> //域、总线、槽、功能号，slot值同一虚拟机上唯一</disk>   <disk type='file' device='cdrom'>//光盘<driver name='qemu' type='raw'/><source file='/home/yeqiang/RedFlag-Asianux-Server-7.5-aarch64-for-Phytium-dvddisc-20210701.iso'/><target dev='hdc' bus='scsi'/><readonly/></disk></devices>
</domain>

define

virsh define redflag.xml

查看

 启动虚拟机

virsh start redflag1

再次查看状态

故障

错误：unsupported configuration: ACPI requires UEFI on this architecture

<cpu mode="host-passthrough"/>

vnc无输出，虚拟机未正常启动

制定bios

<os><type arch='aarch64' machine='virt'>hvm</type><loader readonly='yes' type='pflash'>/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw</loader><nvram template='/usr/share/edk2/aarch64/vars-template-pflash.raw'>/usr/share/edk2/aarch64/QEMU_VARS.fd</nvram></os> 

错误：internal error: qemu unexpectedly closed the monitor: 2023-04-18T08:05:31.354981Z qemu-kvm: Initialization of device cfi.pflash01 failed: device requires 67108864 bytes, block backend provides 786432 bytes

备份，修改大小 

cp /usr/share/edk2/aarch64/QEMU_VARS.fd /usr/share/edk2/aarch64/QEMU_VARS.fd.bak
qemu-img resize -f raw /usr/share/edk2/aarch64/QEMU_VARS.fd 64M

修改效果

没有键盘鼠标

 配置

<devices>节点添加

<input type='tablet' bus='usb'/>
<input type='keyboard' bus='usb'/>

USB is disabled for this domain, but USB devices are present in the domain XML

未完待续。。。
