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.

screenshot of virt-p2v

Description
"Conversion was successful" pop out even virt-p2v fails

Version:
virt-v2v-1.28.1-1.13.el7.x86_64
livecd-p2v-201411201732.iso

How reproducible:
100%

Steps to Reproduce:
1.Launch virt-p2v boot GUI via iso or virt-p2v image.

2.Use virt-p2v to convert a host without operating system installed.

3.The conversion fails and connection closed,then "Conversion was successful" pop out.

Actual results：
As step 3 describes.

Expected results:
In step 3,some info like "Conversion failed" shows.

Additional info:
Screenshot attached.

Background:

The code that pops up the dialog is libguestfs.git/p2v/gui.c:
start_conversion_thread.

Presumably p2v/conversion.c:start_conversion is returning a
success code even when virt-v2v fails.

You can test this by running the ISO like this:

  truncate -s 10G empty
  qemu-kvm -hda empty -cdrom livecd-p2v-XXX.iso -boot d

and then starting a conversion.  It will fail because virt-v2v
cannot convert a disk without an operating system.

John's patch has been accepted upstream:
https://www.redhat.com/archives/libguestfs/2014-December/msg00116.html

Upstream commit:

virt-v2v-1.28.1-1.18.el7.x86_64
livecd-p2v-201412160442.iso

If conversion fails,an box will pop out with the below error:
Conversion failed:virt-v2v exited with status 1.

Tested with:
libguestfs-1.28.1-1.36.el7.x86_64
