qcow2 to bootable iso

[CptCharis]

Hello everybody.
I have a nice installation of arch i3 in my kvm virtual machine and I would like to make it an iso so I can transfer in to a real machine.
I google around and the best way o found is below command

qemu-img convert -f qcow2 -O raw my-qcow2.img /dev/sdb

the command produce a raw image from qcow2 image and copy it into a usb stick.
Once I try to boot up from this usb stick
Arch grub menu page is open normally but after that it drop to
Rootfs
Error msg: device UUID=‘number-of-device’ not found.
Dropped in an emergency shell.
It something that looks normal since the hard disk is not there but is there any way to produce a bootable usb somehow?
Thanks a lot.

G'day Capta , I may not be your Man to help, but can you tell us the source of the linux command for qemu-img?

It may help.

Cheers

I did that once and got it working but it was a long time ago so can't remember exactly what I did, keep in mind if you want this to work with uefi boot your vm/raw image also has to have efi boot enabled. As for converting a virtual machine to a physical machine and viceversa, the Archwiki has a page dedicated to that topic.

OK, bearing in mind that the question there was asked and answered over 9 years ago, conditions may have changed.

Below that one answer are a number of comments dated 2018 through to 2020, they may be more relevant.

One says

qemu-img dd -f qcow2 -O raw bs=4M if=/vm-images/image.qcow2 of=/dev/sdd1

I wonder if that would be likely to work?

Exactly the same situation Chris. Same error.

Thanks. I tried but I faced same other issues.
e.x permission issues with share folders, rsync command not response etc.
anyway keep searching. Thanks again
