[SOLVED] Restoring .qcow2 file after Proxmox reinstallation

[fastrick]

I recently reinstalled Proxmox on my system, and prior to the reinstallation, I had an OMV (OpenMediaVault) virtual machine (VM) running on a 4TB HDD (with 1.5TB of total storage in use). However, after reinstalling Proxmox, I encountered an issue when attempting to mount the disk again using the Proxmox GUI. The only option available was the "Wipe Disk" option, which would erase all the data on the disk.

Upon exploring the Proxmox system, I discovered the presence of the .qcow2 file, which I learned contains the files of the VM. I came across several YouTube tutorials explaining how to restore the .qcow2 file, but unfortunately, I do not have an additional HDD with sufficient capacity to restore the VM.

Edit: Researching I mounted the HDD back to proxmox using

pvesm add dir new-hdd --path /root/NAS.

How to create the VM again using the .qcow2 file?

The most basic way:
qm create 112
qm set 112 -scsi0 new-hdd:vm-112-disk0.qcow

There are many other options available, you can discover them in "man qm", or via GUI after you create the VM and add the disk.
