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

• Tried to migration Ubuntu 22.04 VM from Vmware ESXi whose /usr partition is independent.

  Please provide the package NVR for which bug is seen:

virt-v2v.x86_64 == 1:1.42.0-22.module+el8.9.0+18724+20190c23

libguestfs.x86_64 == 1:1.48.4-4.el9

How reproducible:

This issue is similar to: https://bugzilla.redhat.com/show_bug.cgi?id=1949683

If we try to migrate VM having /usr independent partition then the VM migration using virt-v2v tool fails with following error:

virt-v2v: error: inspection could not detect the source guest (or physical
machine).

Assuming that you are running virt-v2v/virt-p2v on a source which is
supported (and not, for example, a blank disk), then this should not
happen.

Inspection field 'i_arch' was 'unknown'.

The command we used is as follows:
sudo VIRT_V2V_TMPDIR=/tmp/trilio_v2v/Atul-Trialr89vmt_9 LIBGUESTFS_BACKEND=direct /usr/bin/nova-rootwrap /etc/nova/rootwrap.conf virt-v2v -x -v -i libvirt -ic <Libvirt_URI> -o local -os /tmp/trilio_v2v/Atul-Trialr89vmt_9 -ip /tmp/trilio_v2v/Atul-Trialr89vmt_9/tmprrqa7pl8 -it vddk -io vddk-libdir=/opt/vmware-vix-disklib-distrib -io vddk-thumbprint=3c:83:b4:cf:df:df:1d:ef:c2:70:ae:81:94:81:79:0c:97:55:0f:59 – <VM_Name>

Steps to reproduce

1. Create VM having /usr independent partition on vmware ESXi
2. Try to migrate the VM from vmware using virt-v2v tool
3.  

Expected results

v2v should work when /usr is in different partition.

Actual results

v2v is failing with error 'i_arch' was 'unknown' when /usr is in different partition.
