  1. 0. attach HDD to linux machine, and mount VMFS
  2. - vmfs-fuse
  3. - vmfs-tools
  4.  
  5. 1. recover VM system files:
  6. - Host-000001-delta.vmdk    /1st snapshot file/
  7. - Host-000004-delta.vmdk    /2nd snapshot file/  
  8. - Host-flat.vmdk            /VM's filesystem file/
  9.  
  10. 2. generate descriptor file for Host-flat.vmdk:
  11. # cd /vmfs/volumes/4b60b1fa-810d9754-167f-78e7d1f52133/Host  /where my VM was stored/
  12. # ls -la
  13. -rw-r--r--    1 root     root         4865806336 Oct 12 21:17 Host-000001-delta.vmdk
  14. -rw-r--r--    1 root     root        19445207040 Oct 12 21:51 Host-000004-delta.vmdk
  15. -rw-r--r--    1 root     root       214748364800 Oct 12 21:00 Host-flat.vmdk
  16.  
  17. # vmkfstools -c 214748364800 -a lsisata -d thin Host-tmp.vmdk
  18. ## where -c = 214748364800 size of Host-flat.vmdk in bits
  19. ## -a = type of VM's disk
  20. ## Host-tmp.vmdk - name of new vmdk file
  21.  
  22. # cp Host-tmp.vmdk Host.vmdk
  23. # vi Host.vmdk

  51. 3. create NEW VM {named: WWW} ...... add disk -> path to datastore_old/Host -> Host.vmdk
  52. 4. Power_on WWW, boot, make snapshot, shutdown
  53. 5. Edit new VM Snapshot's descriptor file - Host-000002.vmdk in cur dir:
  54. # ls -la
