Running Alpine in Qemu Live mode
If your just want to give Alpine Linux a try, qemu can be used without a disk image and further configuration.
You need to issue
at boot prompt to avoid being forced in graphical mode and loosing access.
Question: Is there a way to pass an apkovl as paramater at this stage?
Response to self: Yes. I do it like this and I mount /dev/vda1 as /media/config to store the apkovl and the apkcache:
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
fdisk /dev/vda mkdosfs /dev/vda1 mkdir -p /media/config echo "/dev/vda1 /media/config vfat rw 0 0" >> /etc/fstab mount /media/config setup-alpine lbu ci
At next reboot, it will use the newly generated apkovl and apkcache stored on /dev/vda1 running in run-from-ram from the latest official ISO.
