Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Created attachment 1451328 [details]
v2v-ubuntu18.04_LTS.log

Description of problem:
Virt-v2v can't convert ubuntu18.04 LTS guest

Version-Release number of selected component (if applicable):
virt-v2v-1.38.2-3.el7.x86_64
libguestfs-1.38.2-3.el7.x86_64
libvirt-4.3.0-1.el7.x86_64
qemu-kvm-rhev-2.12.0-3.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Prepare ubuntu18.04 LTS guest and convert it by virt-v2v to rhv4.2
# virt-v2v ubuntu18.04-LTS -o rhv -os 10.66.144.40:/home/nfs_export
[   0.0] Opening the source -i libvirt ubuntu18.04-LTS
[   0.0] Creating an overlay to protect the source from being modified
[   0.4] Initializing the target -o rhv -os 10.66.144.40:/home/nfs_export
[   0.8] Opening the overlay
[   5.2] Inspecting the overlay
[   8.2] Checking for sufficient free disk space in the guest
[   8.2] Estimating space required on target for each disk
[   8.2] Converting Ubuntu 18.04 LTS to run on KVM
virt-v2v: warning: could not determine a way to update the configuration of
Grub2
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 [...]


Actual results:
As above description

Expected results:
Virt-v2v can convert ubuntu18.04 LTS guest

Verify the bug with builds:
virt-v2v-1.38.2-5.el7.x86_64

Steps:
1.Prepare ubuntu18.04 LTS guest and convert it to rhv4.2 by virt-v2v

    (100.00/100%)
[ 138.3] Creating output metadata
[ 138.4] Finishing off

2.Import guest from export domain to data domain after finishing conversion, power on the guest and checkpoints of guest are passed

3.Convert ubuntu18.04 guest from vmware to libvirt by virt-v2v
# virt-v2v -ic vpx://root.73.141/data/10.73.75.219/?no_verify=1 esx6.7-ubuntu18.04LTS-x86_64 --password-file /tmp/passwd

Pool default refreshed

Domain esx6.7-ubuntu18.04LTS-x86_64 defined from /tmp/v2vlibvirtbb7a13.xml

[1114.6] Finishing off


4.Power on the guest, guest can't obtain IP due to bug1451597, but the other checkpoints of guest are passed


Result:
   Virt-v2v can convert ubuntu18.04 LTS guest now, so move the bug from ON_QA to VERIFIED
