No.

Recommended:

- Add a media to your host where you install Proxmox VE (use the same host name as you had before!)

- copy the database for the pve filesystem from your "killed" version to the newly installed and resinstall the clsuter filesystem by (assuming your old Proxmox installation is mounted on /mnt/temp):

service pve-cluster stop
cp /mnt/temp/var/lib/pve-cluster/config.db /var/lib/pve-cluster/.
pmxcfs -l

Then all your VM config files are available again in the new instalaltion.

Then adapt the config files in order to access the proper virtual disks (which are still on the old Installation) and your VMS are ready for use.

Afterwards you can:

- continue using the new Proxmox installation

- use the new installation just for backup the VMs to an external server before you write over the "killed" version with another Proxmox installation from scratch (where you can restore then the backed up VMs).
