As the title says I'm trying to convert a raw image file to an iso image.
I've used these as reference when doing this.
https://www.turnkeylinux.org/blog/convert-vm-iso
brief (tldr:) (there is an extended background at the bottom, if it helps)
I created a raw image from my qcow2 VM, and mounted this as a loopback device into
virtMachineIMG.mount
When I run the following
xorrisofs -v -J -r -V -o ./MyCentos_img.iso ./virtMachineIMG.mount/
I get an error at the end that the image is too large and cannot be written.
Does anyone have any ideas of how I can get around this?
My raw image file is 8gig in size. I'm not sure exactly how much of this is used, or how to safely 'shrink' the disk to just the size of the data within.
Am I missing a step in my preparation ? should I be creating another disk with qemu that I then burn my raw image onto ?
I should note that my raw image (original qcow2 file) used LVM, does this make a difference?
All help is greatfully accepted, and hugely appreciated.
David.
ps. if you need more details of the verbose output just ask, I can always re-run xorrisofs - it takes about 2 hours to run, is this normal ?
___________ Background : ____________
I've setup up a test system on a local pc in a virtual machine Host : Debian Guest : Centos using : Qemu / KVM inside Virtual Machine Manager.
due to the nature of the test system I needed to 'install from source' and setup all the required parts (Postgres, Tomcat... etc, etc, etc ...).
This went really well, and my colleagues are pleased with what I have done. However so as they aren't required to come to my office I proposed to see if I could make this into a ISO that they could then easily run from anywhere.
Reasoning :
- They could boot into this system from any pc.
- It could be more easily moved to another server (as required).
- Didn't want to trouble my colleagues with needing to install anything, just plug the USB drive with the ISO into your pc, and boot from it directly.
- Also much easier for giving any presentations of the platform.
- can use it to create a VM inside one of our servers for extended testing (I'm making the assumption that an ISO is going to be easier for this, rather than a raw or qcow2)
Obviously if there where rpms or debs of the main part platform (didn't need to install from source), then I would have simply created a CentOS ISO with links to the required rpms to start an install.
Also I want my colleagues to access some 'sample data' within the platform, and this way I can be sure we are all working from the same base.
