To just give Alpine Linux a try in diskless mode, qemu can be used to boot the .iso file without any need for a virtual HDD image or further configuration.
at boot prompt to avoid being forced into graphical mode and losing access.
Letting the .iso image load an apkovl
This works by mounting a persistent filesystem under /media and selecting it to store the apkovl and the apkcache.
Preparing a KVM with a virtual drive:
mkdir -p /media/usb/images qemu-img create -f raw /media/usb/images/mykvm.config 32M qemu-system-x86_64 -enable-kvm -m 384 \ -name mykvm \ -cdrom /media/usb/images/alpine-3.2.0-x86_64.iso \ -drive file=/media/usb/images/mykvm.config,if=virtio \ -net lan \ -boot d &
And inside the KVM (running Alpine Linux):
fdisk /dev/vda #creating a partition mkdosfs /dev/vda1 mkdir -p /media/vda1 echo "/dev/vda1 /media/vda1 vfat rw 0 0" >> /etc/fstab mount -a setup-alpine # (select vda1 for saving configs) lbu commit
The next reboot then loads the generated apkovl and apkcache found on /dev/vda1 -- completely running-from-ram based on the latest official ISO.
