HI i have the same problem. I have a 800 GB image qcow2 file, and I can't mount it to see the content.
I mounted the drive (Sata SSD) to /mnt/data so:
/dev/sda1 916G 101G 770G 12% /mnt/data
I want to open that vm-501.qcow2 so I can recover the files I have there.
That was a Proxmox VM Openmediavult.
I reinstalled the proxmox server and now I can't recover that qcow2.
I follow the steps and I was able to attach the vm-501-disk-0.qcow2 to the new VM I created.
But when I start the VM, the VM doens't boot up.
The boot order I put it on hard disk first, but nothing happens.



Is there a way to make it boot? Or a way to recover the content of the qcow2 file?
Thanks.
