Qemu example archlinux

The following is a really simple, start-to-finish archlinux install within qemu. The purpose of this example is to highlight changes between a regular install, and a qemu install.

Create Disk, Boot Install Media

qemu-img create -f raw hdd.disk 4G     # Create Virtual image
qemu-img resize        hdd.disk +10G   # You can increase disk size if needed

## pop in your arch installation usb, and run the following (sdb being thedisk wih your install media)
sudo qemu-system-x86_64 \
    -hda /dev/sdb \
    -hdb /home/will/dev/megaton.disk \
    -m 2G

NOTE:

You cannot use ping, and nc isn't installed!!

NOTE:

User-Mode networking (slow) will be started automatically as long as no -netdev flag is used when the VM is started. Try pacman -Syu to see it working

Perform Normal Archlinux Install

Normal Install

mkfs.ext4 /dev/sdb1      # Format partition
mount /dev/sdb1 /mnt
pacstrap -i /mnt base
genfstab -p /mnt >> /mnt/etc/fstab

arch-chroot /mnt

pacman-db-upgrade
pacman -Syu
pacman -S grub-bios vim git zsh sudo tmux
visudo
