試作機器: orangePi 6G,

1. using qemu-img to create a disk image

qcow2 (QEMU Copy-On-Write 2) is a disk image file format used with QEMU. It is a popular and efficient file format for managing virtual machine disk images.

$ mkdir qemu-proj && cd $_
 qemu-img create -f qcow2 debian-12.2.0-amd64.qcow2 16G
Formatting 'debian-12.2.0-amd64.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=17179869184 lazy_refcounts=off refcount_bits=16

2. Download debian net installer, or iso-dvd Image

$ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-12.2.0-amd64-netinst.iso

$ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-12.2.0-amd64-DVD-1.iso

3. Installing the operating system

$ qemu-system-x86_64 \
-m 512 \
-boot order=d \
-cdrom debian-12.2.0-amd64-netinst.iso \    --> failed to configure the network
debian-12.2.0-amd64.qcow2

-enable-kvm \                      <--- ??? take it

-m 512 --> 512M -m 2G allocate 2G

$  qemu-system-x86_64 -m 2G \
-boot order=d \
-cdrom debian-12.2.0-amd64-DVD-1.iso debian-12.2.0-amd64.qcow2
