i think the max bandwidth limitation would not exceed 0x7fffffff(2147483647). Since because of your configuration of RX_TX factor for 1GB/s network exceeds the max limit the vmware server is throwing error.

Also, in your log 2147483 is truncation of 2147483647

Title:
  Failing to launch VM if RX_TX*Network Qos is greater than Maximum
  value is 2147483

Status in OpenStack Neutron (virtual network service):
  Opinion

Bug description:
  Unable to launch VMs when net QOS rate that is RX_TX of flavor
  multiplied by Network QOS max bandwidth value is greater than 2147483.

  ERROR Server Error Message: Invalid bandwidth settings. Maximum value
  is 2147483.

  
  If default bandwidth is 1 GB/s and RX_TX for a flavor is set to 5 it does not work and fails while launching instance.
