Problem conclusion

• The issue was that the Backup-Archive client sends incorrect
  type (DYNAMIC instead of FIXED) of the virtual disk to the TSM
  server. As result: after restore virtual machine has DYNAMIC
  disk instead of FIXED virtual disk. It doesn't have influence on
  VM, that is VM starts and works. The issue has been fixed, now
  we send the correct type of VM disk to the server.
