Convert .iso to .qcow2

Question

I would like to convert windows .iso to .qcow2 format and use in openstack.

Tried using vbox: https://www.virtualbox.org/ Not sure how to add cloud-init package to the OS, configure grub (steps 11&12)

Also tried using qemu-img commands in windows using ref https://cloudbase.it/qemu-img-windows/ able to convert image to .qcow2 format but when i upload image to openstack and launch instance. It got stuck at booting.

Answer 1

I think you have to install it first before converting it, try to install it on virtualbox and then convert virtualbox image to qcow2.

Hope it will help

Answer 2

qemu-img convert -O qcow2 virtio-win.iso virtio-win.qcow2

Answer 3

brew/apt install qemu
qemu-img convert xxx.iso xxx.qcow2

It surprised me that the post still alive after years.

And the below comment answered the updated question correctly. qemu works fine, tho Google compute engine OS detection does not able run it. That's why it failed on them.
