安裝前準備

創建密碼配置文件，否則虛機啟動后無法登錄

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

安裝虛機

創建虛機鏡像磁盤

qemu-img create -f raw boot-image-qemu.hddimg 16G
xzcat wr-distro-*-metal.x86_64.raw.xz | dd of=boot-image-qemu.hddimg conv=notrunc

創建并啟動虛擬機

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

執行報錯：qemu-system-x86_64: -fw_cfg:?invalid option

問題定位：

fw_cfg參數已經不再支持，但是并沒有找到替代參數：
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.

解決：

yum install centos-release-qemu-ev
yum 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執行，需要將qemu-system-x86_64替換為：/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

現場機器回顯，和上面下載的distro23不太一樣。可能是版本差異。

解鎖鏡像（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.

解鎖命令：ostree admin unlock --hotfix

解鎖后，再次安裝就可以了
~# cat /etc/lsb-release
