Use the Proxmox shell to import the NSv image disk.
Command Syntax:
qm importdisk <VM-id> <NSv image location> <storage name>
Example:
qm importdisk 101 sw_nsv_-kvm.8.0.0-8026-R6526.wic.qcow2 local-lvm
The Import Disk to VM operation must be executed by the root user from the Proxmox shell. When the command was run using a non‑root user account—even with full administrative permissions—the qm command was not recognized. Logging in to the shell as the root user allowed the command to execute successfully.
