VB4AWS/VBR Linux EC2 Restore from backup copy

[netwichi]

I took a backup of RHEL9 using VB4AWS and then created a backup copy using VBR.

The EBS device name of the original EC2 instance was as follows:
/dev/sda1
/dev/sdb

I have confirmed that when I perform a "Restore to Amazon EC2" from the backup copy using VBR, the EBS device name changes to the following:
/dev/sda1
/dev/xvdf

Is this a feature?
It seems strange that the EBS on a RHEL EC2 instance is restored with the device name /dev/xvdf.
