What were you trying to do that didn't work?

The /var/lib is bind mounted in a Ubuntu VM:

ubuntu22:~# cat /etc/fstab |egrep "sdb|lib"
/dev/sdb /data xfs defaults 0 1
/data/lib /var/lib none bind 0 0

While converting this VM from vMware to OpenShift Virtualization, migration is failing with following error:

libguestfs: trace: v2v: filesize "/var/lib/dpkg/status"
guestfsd: => inspect_get_package_format (0x1e5) took 0.02 secs
guestfsd: <= filesize (0xda) request length 64 bytes
guestfsd: error: /var/lib/dpkg/status: No such file or directory
gulibguestfs: trace: v2v: filesize = -1 (error)
libguestfs: trace: v2v: inspect_list_applications2 = NULL (error)
virt-v2v: error: libguestfs error: filesize: /var/lib/dpkg/status: No such file or directory

This is because it's not mounting the /data/lib to /var/lib when it tries to find the Kernel package at "/var/lib/dpkg/status". Problem is only with bind mounts and I cannot reproduce the issue if I mount directly on a different disk. Looks like v2v is ignoring the bind mount entries.

v2v: inspect_get_mountpoints = ["/data", "/dev/sdb", "/boot/efi", "/dev/disk/by-uuid/1B12-24EF", "/boot", "/dev/disk/by-uuid/6f979251-660f-415e-897f-401549c5aa81", "/", "/dev/disk/by-id/dm-uuid-LVM-nVVMRcaYjNNfO6PUBPqTHh7ktCebXL0iXkyyNQf1ydZmX9fj2ANwOA18PQNdrYmh"]

What is the impact of this issue to you?

Please provide the package NVR for which the bug is seen:

virt-v2v 2.5.6

Migration Toolkit for Virtualization Operator   2.7.9

How reproducible is this bug?:

100%

Steps to reproduce

1.  Created an Ubuntu VM in vMware. Added a new disk and mounted the new disk at "/data/". Moved  /var/lib/ to new disk. 
2.  Bind mounted the /data/lib to /var/lib
3.  Try converting the VM to OpenShift Virtualization using MTV. Migration failed with the above error. 

Expected results

The Ubuntu VM migration from vMware fails if /var/lib/ is bind-mounted
