02 Installation steps
The installation process is more convenient with the latest QEMU_EFI_8.0.fd. The basic default options are fine.
02.01 Generate virtual machine files
:: Create directory mkdir e:\work\202309\loongarch & & cd e:\work\202309\loongarch :: Generate image disk file, qemu is installed in the d:\install\qemu directory d:\install\qemu\qemu-img create -f qcow2 archlinux-loongarch001.qcow2 2048G ::The running results are as follows :: Formatting 'archlinux-loongarch001.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=2199023255552 lazy_refcounts=off refcount_bits=16
02.02 Installing the system
02.02.01 Start the virtual machine
Firmware directory: E:\work\202309\loongarch\QEMU_EFI_8.0.fd
The virtual machine file generated previously: E:\work\202309\loongarch\archlinux-loongarch001.qcow2
Image file: E:\tools\os\loong64\archlinux-loong64.iso

After startup, the following interface appears, select the default item *Arch Linux install medium (loong64,UEFI)
After pressing Enter, you will enter the following interface. After a short wait, you will enter the configuration interface.
02.02.02 Set configuration items
Enter the configuration interface
Here we focus on configuring disk, root password, user account, audio, network, time zone
Disk
After saving, you can select the disk configuration again to see the specific information to ensure that it has been allocated successfully.
Login account
After changing the root password, remember to create a commonly used user for yourself (for example: user01). After setting the password, remember to set sudo to True.
Audio: Pulseaudio
Network: Copy the network configuration from the ISO to the installation
Time zone: Asia/Shanghai
Click Install and then Enter to start the installation
02.02.03 arch-chroot
This step is very important.
The default installation process will automatically prompt arch-chroot .
If there is no such process, manual configuration is required. Please refer to: Configuring Loongson New World Environment using QEMU
Basic Information:
cat /proc/cpuinfo
uname -a cat /proc/version cat /etc/issue g++ --version
03 Install other software
Install the software using sudo pacman -Sy
sudo pacman -Sy base linux linux-firmware base-devel sudo zsh fish grub efibootmgr xfce4 xfce4-goodies lightdm lightdm-gtk-greeter noto-fonts-cjk noto-fonts-emoji btrfs-progs xfsprogs dosfstools exfatprogs f2fs-tools xfsprogs networkmanager nano fcitx5 fcitx5-configtool fcitx5-chinese-addons neofetch vim git curl wget
# After setting the default startup service, start it again to enter the xfce4 graphical startup interface. systemctl enable lightdm.service systemctl enable NetworkManager.service
Run the following command to enter the graphical interface
d:\install\qemu\qemu-system-loongarch64 ^
-m 8G ^
-cpu la464-loongarch-cpu ^
-machinevirt^
-smp 4^

-hda E:\work\202309\loongarch\archlinux-loongarch001.qcow2
After entering the password and pressing Enter, enter the graphical interface.
You can input normally,but the mouse focus is slightly shifted.
