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

Tested on a SLES 15 SP6 VMware virtual machine which have the package kernel-source-6.4.0-150600.23.38.1.noarch installed.

Migrating this VM to OpenShift Virtualization using MTV  is failing with following error while querying the "kernel-source" package:

libguestfs: trace: v2v: command_lines "rpm -ql kernel-source-6.4.0-150600.23.38.1"
commandrvf: rpm -ql kernel-source-6.4.0-150600.23.38.1
guestfsd: error: guestfsd: failelibguestfs: trace: v2v: command_lines = NULL (error)
virt-v2v: error: libguestfs error: command_lines: guestfsd: failed to encode reply body
(maybe the reply exceeds the maximum message size in the protocol?)

I think it is hitting the GUESTFS_MESSAGE_MAX limit. The output of rpm -ql kernel-source-6.4.0-150600.23.38.1 is huge:

192:~ # rpm -ql kernel-source-6.4.0-150600.23.38.1 |wc -c
5177681

Migration works if I remove the kernel-source from the source VM.

What is the impact of this issue to you?

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

virt-v2v-2.7.1-4.el10.x86_64
libguestfs-1.54.0-5.el10.x86_64
guestfs-tools-1.52.2-2.el10.x86_64

How reproducible is this bug?:

100 %

Steps to reproduce

1. Create OpenSuse/SLES 15 VM in the vMware.
2.  Install the Kernel source package in the VM using the command "zypper install kernel-source".
3.  Try converting this VM. Conversion fails with above error.

Expected results

Migration a SUSE VM that have kernel-source package installed should work .
