View source for Running Alpine in Live mode in QEMU

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.

{{Cmd|qemu-system-x86_64 -m 512 -nic user -boot d -cdrom alpine-{{AlpineLatest}}-x86_64.iso --accel kvm}}
== 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:
{{cmd|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-{{AlpineLatest}}-x86_64.iso \
-drive file{{=}}/media/usb/images/mykvm.config,if{{=}}virtio \ 
-net lan \
-boot d &}}

And inside the KVM (running Alpine Linux):

<pre>
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
</pre>

The next reboot then loads the generated apkovl and apkcache found on /dev/vda1 -- completely ''running-from-ram'' based on the latest official ISO.
