Command hvrfingerprint causes HVR to calculate and display the hardware fingerprint of the current host it is running on. A host fingerprint is an upper case letter followed by 6 decimal digits, such as P654321.

Hardware fingerprint of an Amazon EC2 virtual machine will be reported with an 'A' letter, such as A654321. Only EC2 instance id is used in this case for fingerprinting. The fingerprint stays the same even if EC2 virtual machine migrates to a different hardware.

This command should be used on the hub host to learn its fingerprint. Host fingerprint of the hub host is also displayed in hvrgui.
