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.

Log file of virt-p2v

Description
Improve the log info in virt-p2v log file

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

4.Check virt-p2v log file,error info shows as below:
virt-v2v: error: no root device found in this operating system image.

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

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


Actual results：
In step 4,error info like "If reporting bugs, run virt-v2v with debugging enabled and include the complete output:virt-v2v -v -x [...]" shows.

Expected results:
In step 4,error info like "If reporting bugs, run virt-v2v with debugging enabled and include the complete output:virt-v2v -v -x [...]" should be removed.

Additional info:
Attach the log file.

Can you please explain why?

This log info comes from virt-p2v,I think you can not use virt-v2v -v -x to get virt-p2v debug info.
Comment 4 Richard W.M. Jones 2014-11-25 10:11:52 UTC 
Tricky to implement since as far as virt-v2v is concerned
we're just running virt-v2v.  In any case this is cosmetic so
I'm moving it to RHEL 7.2.
Comment 6 Richard W.M. Jones 2015-05-15 10:19:10 UTC 
I have a patch series which fixes this, but it's very invasive
so it's not RHEL 7.2 material.  However we are rebasing in RHEL 7.3
so we should be able to pick up the fix there.

The patches have been posted upstream:

Comment 11 Richard W.M. Jones 2016-06-27 17:42:07 UTC 
I feel we should remove the "Enable server-side debugging"
button as well.

Comment 16 kuwei@redhat.com 2017-03-20 07:04:36 UTC 
Hi, rjones
 
Could we make a p2v(1.36.2-2) bootable usb key by virt-p2v-maker to test the bug or waiting you to build a  virt-p2v ISO ?

According to comment 15, We also could see  the info "virt-v2v -v -x ... >& log" in virt-v2v log file on the virt-v2v conversion server. I think the bug has not been fixed. Could you help to check this ?

Pino is waiting to build virt-p2v ISO.  There is some problem with
brew that stops it from being built at the moment.

However testing this using virt-p2v-maker should give the same results.

Can you attach the full virt-p2v-conversion-log file from
this run please.
