RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 2 mxie@redhat.com 2022-06-09 07:19:01 UTC 
Reproduce the bug with below builds:
virt-v2v-1.42.0-18.module+el8.6.0+14480+c0a3aa0f.x86_64
libguestfs-1.44.0-5.module+el8.6.0+14480+c0a3aa0f.x86_64
nbdkit-1.24.0-4.module+el8.6.0+14480+c0a3aa0f.x86_64
libvirt-8.0.0-5.2.module+el8.6.0+15256+3a0914fe.x86_64
qemu-kvm-6.2.0-11.module+el8.6.0+15489+bc23efef.1.x86_64


Steps to reproduce:
1. Prepare a rhel8.6 guest and do below in guest on VMware
#rm -rf /var/lib/rpm/_db.*
#vi /var/lib/rpm/_db.001 (create a empty _db.001)

2. Convert the guest from VMware by v2v
# virt-v2v -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 -it vddk -io vddk-libdir=/home/vddk7.0.3 -io  vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21 -o rhv-upload -of qcow2 -oc https://dell-per740-22.lab.eng.pek2.redhat.com/ovirt-engine/api  -op /home/rhvpasswd  -os nfs_data -b ovirtmgmt -ip /home/passwd esx7.0-rhel8.6-bug2093415

virt-v2v: error: no installed kernel packages were found.

This probably indicates that virt-v2v was unable to inspect this guest 
properly.

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]


Verify the bug with below builds:
virt-v2v-1.42.0-19.module+el8.6.0+15577+2ffd6ffa.x86_64
libguestfs-1.44.0-5.module+el8.6.0+14480+c0a3aa0f.x86_64

qemu-kvm-6.2.0-11.module+el8.6.0+15489+bc23efef.1.x86_64

Steps:
1.Update virt-v2v and convert the guest again
