    2017-08-07T09:40:18.356Z| vmx| I125: HotPlug: Hot-add of scsi1 failed.


This error occurs when the file /etc/vmware/config contains a syntax error such as double curved quotes like these ones < “ .... ” >.

  • Bad syntax: vmx.fullpath = “/bin/vmx”
  • Good syntax: vmx.fullpath = "/bin/vmx"


To resolve the issue, change the double curved quotes < “ .... ” > with the double standard quotes < " .... ">.
