Hello everyone!
I have been learning QEMU for the past day and so I’ve almost finished building my perfect VM from the qemu cli, and I was wondering if there is any method to say, copy a partition(+bootloader) of a physically installed system (in this case, Windows) over a hard disk image and run it with QEMU
Unfortunately I’ve had no luck searching online about it and I’m unsure how to proceed myself since I’ve never done any disk-cloning or anything like that
My best guess would be to dump the contents of the partitions into a shared folder with the VM, then use a live media to copy those contents over into the hard disk image and finally install a bootloader to work with the Windows boot manager, but I’m all ears for what anyone has to say about it.
Thanks for reading and please let me know what you know!
I also wanted to put an emphasis on how working with virtual disks is very much the same as real ones. Same well known utilities to copy partitions work perfectly fine. Same cgdisk/parted and dd dance as you otherwise would.
Technically if you install the
arch-install-scriptspackage on your host, you can even install ArchLinux into a VM exactly as if you were in archiso with the comfort of your desktop environment and browser. Straight uppacstrapit directly into the virtual disk.Even crazier is, NBD (Network Block Device) is generic so it’s not even limited to disk images. You can forward a whole ass drive from another computer over WiFi and do what you need on it, even pass it to a VM boot it up.
With enough fuckery you could even wrap the partition in a fake partition table and boot the VM off the actual partition and make it bootable by both the host and the VM at the same time.
Learning to use QEMU I started to grasp those possibilities actually, now getting these tips I do feel like I could dive into lots of “sandboxing” and generally be able to try anything with it, my only constrain now shall be disk space
