安装前准备
创建密码配置文件，否则虚机启动后无法登录
cd /var/lib/libvirt/images/disks/windriver/
docker run -ti --rm quay.io/coreos/mkpasswd --method=yescrypt 123456 >password_hash.txt
cat <<-ENDOF> sample.bu
variant: fcos
version: 1.4.0
passwd:
users:
- name: root
password_hash: `cat password_hash.txt`
ENDOF
docker run --rm -v $(pwd)/sample.bu:/config.bu:z windriver/wrdistro23:butane --pretty --strict /config.bu > ./sample.ign
安装虚机
创建虚机镜像磁盘
qemu-img create -f raw boot-image-qemu.hddimg 16Gxzcat wr-distro-*-metal.x86_64.raw.xz | dd of=boot-image-qemu.hddimg conv=notrunc
创建并启动虚拟机
qemu-system-x86_64 -net nic -net user -m 4096 \-cpu host -enable-kvm \-fw_cfg name=opt/com.coreos/config,file=./sample.ign \-drive if=pflash,format=qcow2,file=/var/lib/libvirt/images/disks/windriver/OVMF_CODE.fd \-drive if=pflash,format=qcow2,file=/var/lib/libvirt/images/disks/windriver/OVMF_VARS.fd \-drive if=none,id=hd,file=/var/lib/libvirt/images/disks/windriver/boot-image-qemu.hddimg,format=raw \-device virtio-scsi-pci,id=scsi \-device scsi-hd,drive=hd \-nographic
执行报错：qemu-system-x86_64: -fw_cfg: invalid option
问题定位：
fw_cfg参数已经不再支持，但是并没有找到替代参数：
As of QEMU v2.4, writes to the fw_cfg data register are no longer supported, and will be ignored (treated as no-ops)!
As of QEMU v2.9, writes are reinstated, but only through the DMA interface (see below). Furthermore, writeability of any specific item is governed independently of Bit14 in the selector key value.

解决：
yum install centos-release-qemu-evyum update qemu-kvm-ev/usr/libexec/qemu-kvm --help|grep fw[,bootfile=f][,hostfwd=rule][,guestfwd=rule][,smb=dir[,smbserver=addr]]-fw_cfg [name=]<name>,file=<file>add named fw_cfg entry with contents from file-fw_cfg [name=]<name>,string=<str>add named fw_cfg entry with contents from string
使用更新后的命令再次执行，需要将qemu-system-x86_64替换为：/usr/libexec/qemu-kvm
/usr/libexec/qemu-kvm -net nic -net user -m 4096 \-cpu host -enable-kvm \-fw_cfg name=opt/com.coreos/config,file=./sample.ign \-drive if=pflash,format=qcow2,file=/var/lib/libvirt/images/disks/windriver/OVMF_CODE.fd \-drive if=pflash,format=qcow2,file=/var/lib/libvirt/images/disks/windriver/OVMF_VARS.fd \-drive if=none,id=hd,file=/var/lib/libvirt/images/disks/windriver/boot-image-qemu.hddimg,format=raw \-device virtio-scsi-pci,id=scsi \-device scsi-hd,drive=hd \-nographic

现场机器回显，和上面下载的distro23不太一样。可能是版本差异。

解锁镜像（Unlock the image）
By default, the images are locked and do not allow any updates. You must run the following command to ensure your package updates are successful.
~# dnf -y install lsb-release……RPM: error: can't create transaction lock on /usr/share/rpm/.rpm.lock (Read-only file system)The downloaded packages were saved in cache until the next successful transaction.You can remove cached packages by executing 'dnf clean packages'.Error: Could not run transaction.
解锁命令：ostree admin unlock --hotfix
解锁后，再次安装就可以了~# cat /etc/lsb-releaseDISTRIB_ID=wrdistroDISTRIB_RELEASE=23.20240109.3.0DISTRIB_CODENAME=wrdistroDISTRIB_DESCRIPTION="Wind River Linux Distro 23.20240109.3.0"
