 ## GRUB
 
 Update GRUB after `grub` package is updated. Replace `/boot` with your mount
 point of the EFI partition in `--efi-directory=/boot`. Replace `GRUB` with your
 bootloader id in `--bootloader-id=GRUB`.

 #### Install Certs From Docker
 
 Remember to [setup ssl and curl](#setup-ssl-certificates-and-curl) first.
 
-```bash-session
-# curl -fsSL https://download.docker.com/linux/debian/gpg \
->   -o /etc/apt/keyrings/docker.asc

 #### Add Docker Repos
 
-```bash-session
-# echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] \
->   https://download.docker.com/linux/debian \

+```sh
+apt-get update
+apt-get install docker-ce docker-ce-cli containerd.io \
+  docker-buildx-plugin docker-compose-plugin
 ```
 
 #### Start And Enable Docker
 
 Remember to log out and log back to let user group change take effects.
 
-```bash-session
-# systemctl enable docker
-# systemctl start docker
-# groupadd -f docker
-# usermod -aG docker $USER

+## Mirrors
+
+The mirror has to be `debian-ports`, not `debian`, and many mirror sites do not
+provide it. Following is aliyun mirror:
+
+```txt
+/etc/apt/sources.list
+---
+deb https://mirrors.aliyun.com/debian-ports/ unstable main
+deb https://mirrors.aliyun.com/debian-ports/ unreleased main
+deb-src https://mirrors.aliyun.com/debian/ unstable main
+```
+
+The hurd-amd64 deb-src seems to not work.
+
+## Use QEMU Virtual Machine
+
+For i386, use
+
+```sh
+qemu-system-x86_64 -enable-kvm -m 4G \
+  -net nic -net user,hostfwd=tcp::3222-:22 \
+  -vga vmware -drive cache=writeback,file=[...]
+```
+
+For x86_64, use
+
+```sh
+qemu-system-x86_64 -enable-kvm -m 8G -machine q35 \
+  -net nic -net user,hostfwd=tcp::3223-:22 \
+  -vga vmware -drive cache=writeback,file=[...]
+```
+
+GRUB in the image seems to use hard-coded path of `/dev/*` block file as the
+root partition in the kernel command line rather than GUID, so if the hard disk
+bus is changed in QEMU and the path is changed accordingly, the system can't
+boot on.
+
+QEMU cli arguments `-machine q35` enables AHCI and SATA, and is **required for
+official x86_64 image to boot**. As for i386, I haven't checked now.
+
+There is [a Deno script](https://github.com/crupest/crupest/blob/dev/deno/tools/manage-vm.ts)
+written by me to help define and build QEMU cli arguments of VMs.
