I will try and summarise in brief; The initial problem was the machine type I had set in various snapshots/VM's had been deprecated and thus rendered the snapshots all unusable after upgrading O/S (that came packaged with newer libvirt/qemu versions.) I thus needed a simple, intuitive way to edit the snapshots to a machine type that was still supported, permanently. snapshot-edit seemed the appropriate tool for doing this, but alas it would not, a way was needed to force it to save the changes. One of my main reasons for using vm/snapshots is testing software install behaviour/compatibility in Windows, so I have a variety of Windows versions, each with snapshots taken with various levels of core 'things' installed (.net framework , C++ redistributables etc.) Thus the snapshots could be many years old. I need to be able to flick between them, so being able to permanently 'fix' them is my goal. The second issue was similarly being able to edit other 'simple' facets of the snapshots e.g. Attached disks, floppies or ISO's - or paths to them. Memory, if testing something that needed more than I ever invisaged way back when. MAC address (we have to register devices on the network via MAC, which expire, and can then render the snapshot unusable if I cannot change the MAC in the snapshot) I hope this makes sense, I have tried to be brief, I can elaborate further if needed. I think being able to edit existing snapshots simply, with once command, would be very beneficial to many people. (I think most people trying to do this would be aware of the risks, especially if the alternative is that the snapshot doesn’t work anyway.)
