Cannot migrate VM with multi boot - add "--root" option

[gengiskahn]

Hello,
If a VM has several boot options, Virt_v2v defaults the "--root" option to "ask".
Since the program is not run in an interactive shell, virt_v2v exits with an error.

`Dual- or multi-boot operating system detected. Choose the root filesystem
that contains the main operating system from the list below:

[1] /dev/sys1/rootfs (Red Hat Enterprise Linux 9.2 (Plow))
[2] /dev/sys2/rootfs (Red Hat Enterprise Linux 9.2 (Plow))

Enter a number between 1 and 2, or ‘exit’: virt-v2v-in-place: error: exception: End_of_file`

Would it be possible to add the "--root" argument to the cutover command?
