IOSXR - bsdtar: Error opening archive: Unrecognized archive format

[xppratibha]

I ran the following command 👍

./iosxr_iso2vbox.py -s -v xrv9k-fullk9-x.vga-6.5.1.iso.

Then went to "/home/root/cisco_xrv/iosxrv-x64-vbox/machines/xrv9k-fullk9-x.vga-6.5.1"

Executed the below commands:

1. vagrant init 'IOS XRv' , then

2. [root@root xrv9k-fullk9-x.vga-6.5.1]$ vagrant box add --name 'IOS XRv' xrv9k-fullk9-x.vga-6.5.1.vbox --force
   ==> box: Box file was not detected as metadata. Adding it directly...
   ==> box: Adding box 'IOS XRv' (v0) for provider:
   box: Unpacking necessary files from: file:///home/root/cisco_xrv/iosxrv-x64-vbox/machines/xrv9k-fullk9-x.vga-6.5.1/xrv9k-fullk9-x.vga-6.5.1.vbox
   The box failed to unpackage properly. Please verify that the box
   file you're trying to add is not corrupted and try again. The
   output from attempting to unpackage (if any):

bsdtar: Error opening archive: Unrecognized archive format

[root@root xrv9k-fullk9-x.vga-6.5.1]$

Any idea why it is failing ?
