Installing alpine using qemu on android

• Install termux
• Install qemu

pkg install qemu-system-x64_64 qemu-utils

• Download alpine iso

curl https://dl-cdn.alpinelinux.org/alpine/v3.18/releases/x86_64/alpine-virt-3.18.0-x86_64.iso -o alpine.iso

• Create an image disk(to install alpine):

qemu-img create -f qcow2 alpine.img 64g

• Start qemu

qemu-system-x86_64 -hda alpine.img -cdrom alpine.iso -boot d -m 512 -nographic

• edit /etc/resolv.conf to have the content nameserver 8.8.8.8
• Make the resolv.conf file immutable using¹
  • sudo chattr +i /etc/resolv.conf
  • I had issues during setup-alpine and configuring eth0 interface. The resolv.conf was overridden.
• Do setup-alpine
  • setup everything as required
  • For the disk choose sda which is the image that we created.
• Once the installation is done run halt. Exit from Qemu using ctrl+a x
• Boot into the system using

qemu-system-x86_64 -hda alpine.img -boot c -m 1024 -smp 2 -nographic
