  If the virtual machine remains under high business load for a long time and the application is moderately sensitive to performance, it is recommended to enable auto-convergence mode to improve migration success rates.

  Note: If hardware compatibility errors occur during hot plugging or if the hardware device is not supported, this option can be disabled.

If set to None, certain operating systems may experience compatibility issues.
  Note: This parameter is hidden when the location of the virtual machine is set to either cluster or auto-allocated.
