- 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

- 增加 vCPU
預設 QEMU 只有 1 vCPU,要改善 AIX 的效能,可以視硬體等級增加更多 vCPU。
qemu-system-ppc64
啟動參數加上
-nographic -smp 2,sockets=2,cores=1,threads=1
- 增加虛擬網卡裝置
qemu-system-ppc64
啟動參數設置兩個虛擬網卡
-net nic \
-net nic \
-net tap,script=no,ifname=tap0 \
如果要榜定 mac addr.
-net nic,macaddr=56:44:45:30:31:31 \
-net nic,macaddr=56:44:45:30:31:32 \
-net tap,script=no,ifname=tap0 \
