其他管理工作

- 掛載 CD ISO 檔

修改qemu 啟動參數 -cdrom /path/to/your-cd.iso

- 增加第2顆虛擬硬碟

在 Linux 主機：新增 5G 虛擬磁碟 hdisk1.qcow2

cd aix72VM
qemu-img create -f qcow2 hdisk1.qcow2 5G

修改啟動指令，新增兩行參數

-drive file=hdisk1.qcow2,if=none,id=drive-virtio-disk1 \
-device scsi-hd,drive=drive-virtio-disk1 \

完整啟動參數

qemu-system-ppc64 -cpu POWER8 \
