#178 Cannot boot from a cloned Linux with KVM

No, the way you mount LV is not really correct.
You can try:
1. sudo -i
2. ocs-lvm2-start
3. lvscan
With the results, you should be able to find the LV device name, say, it's /dev/r100/root, then you can :
mount /dev/r100/root /mnt
Your files should be in /mnt/ now.

From the photo you posted (https://sourceforge.net/p/clonezilla/support-requests/_discuss/thread/c7f8a3e25d/71fe/9f73/attachment/RescueMode_2024-05-07.PNG), it seems your data are in /dev/sda2 and /dev/mapper/r100-root. Therefore you can mount them and copy files.
As for restoring the image to another type of VM, well, it might let you boot and enter the system you have restored.

So any progress there?
It occurred to me that maybe you can try to restore the image to a VM on different type of software, e.g., virtualbox or VMWare workstation.

Did ou try to mount the device you have? If the cloning finished, and the cloned OS failed to boot, it's only a matter of booting issue. Your data still exist and you should be able to mount and copy them.
BTW, you have two posts, and I suggest you focus on one of them.

I am currently traveling, so I will be online sometimes.
Your case looks like is only the booting issue since you mentioned your system entered rescue mode. As I mentioned, have you used Rocky Linux rescue mode to recreate the initrd?
It should be something like:

Have you tried the latest one, e.g., 3.1.2-22 or 20240408-noble:

BTW, maybe you can try update the initrd using the Rocky Linux rescue disk to do that. Just google "rocky linux rescue disk" and you should find some info.

I would also like to add one more symptom (looks strange to me at least). When I insert the clone disk while the system is running - being booted from the source disk - the system does not even see it. Should it be like this?
Thank you!

Cannot boot from a cloned Linux with KVM

I was trying to boot the system replacing the system disk with the newly made clone (using Clonezilla ver. 3.1.2-9-amd64) - and it failed miserably taking me into the emergency mode. The system Is Rocky Linux (which serves as a KVM-based virtual host for a secondary OS). I would like to understand what could go wrong and whether I need to do any changes to that clone in order to make it bootable - and how to make those changes.
