      Description

      Multiextent support seems to be back by default with ESXi 6.5. The checks done in VMware.pm::check_multiextent are generating warnings and a critical message:

      VMware.pm:check_multiextent|6804| ---- WARNING ----
      VMware.pm:check_multiextent|6804| 2017-07-19 13:13:12VMware.pm:check_multiextent|6804|failed to load multiextent kernel module on vmhost1, exit status: 1, output:

      VMware.pm:check_multiextent|6807| ---- CRITICAL ----
      VMware.pm:check_multiextent|6807| 2017-07-19 13:13:12VMware.pm:check_multiextent|6807|multiextent kernel module is disabled on VM host vmhost1, operations on 2GB sparse virtual disk files will fail
      VMware.pm:check_multiextent|6807| ****************************************************************************************************
      VMware.pm:check_multiextent|6807| DO THE FOLLOWING TO FIX THIS PROBLEM:
      VMware.pm:check_multiextent|6807| Enable the module by running the following command on each VMware host: 'vmkload_mod -u multiextent'
      VMware.pm:check_multiextent|6807| Add a line containing 'vmkload_mod -u multiextent' to /etc/rc.local.d/local.sh on each ESXi host
      VMware.pm:check_multiextent|6807| ****************************************************************************************************
      VMware.pm:check_multiextent|6807| ( 0) VMware.pm, check_multiextent (line: 6807)
      VMware.pm:check_multiextent|6807| (-1) test.pm, process (line: 96)
      VMware.pm:check_multiextent|6807| (-2) vcld, make_new_child (line: 601)
      VMware.pm:check_multiextent|6807| (-3) vcld, main (line: 353)
      

      The version should be checked in the subroutine and the checks bypassed if >= 6.5.
