Subject: [PATCH] Force use of /lmn/media/USER share for legacy VMs

- Introduced VMLEGACY environment variable to ensure that old VMs
  utilize the legacy media share located at /lmn/media/USER.
- This change is aimed at maintaining compatibility with older
  virtual machines that rely on the previous media share structure.
