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.

Description Rita Wu 2011-02-17 08:38:07 UTC 
Description of problem:
virt-inspector will report error message when swap is recorded via UUID in fstab.

fstab entry in rhel4u8 VM:

How reproducible:
always

Steps to Reproduce:
1. # virt-inspector --perl rhel4-32-hvm-min.img
unknown filesystem UUID d7c01559-d48e-4951-829f-ba926cb73719
$VAR1 = '/dev/sda1';
$VAR2 = {
          'initrd_modules' => {
                                '2.6.9-89.EL' => [
                                                   'lib/ext3.ko',
                                                   'lib/jbd.ko'
                                                 ]
                              },
          'arch' => 'i386',
          'apps' => [
                      {
                        'epoch' => undef,
                        'arch' => 'i386',
                        'version' => '3.15.2',
                        'name' => 'MAKEDEV',
                        'release' => '3'
...
  
Actual results:
unknown filesystem UUID d7c01559-d48e-4951-829f-ba926cb73719

Expected results:
No warning about 'unkown filesystem UUID'

Additional info:
Comment 1 Richard W.M. Jones 2011-03-08 08:28:53 UTC 
This is just a warning and the fix is not so trivial.
Moving to 6.2.
Comment 2 Richard W.M. Jones 2011-06-10 09:16:19 UTC 
Matt, is this going to be fixed by the rebase of virt-v2v
in 6.2?  It seems that it will be, if we move to using
the core inspection code.
Comment 3 Richard W.M. Jones 2011-06-10 09:58:48 UTC 
Answer is yes, so we should be able to fix this more
easily in 6.2.
Comment 4 Richard W.M. Jones 2011-08-10 17:20:11 UTC 
Sorry, I have totally misunderstood this bug (my fault, not
the reporter).  Although the bug is in Perl inspection code,
it affects virt-inspector (old version) not virt-v2v.

I will try to look at this tomorrow.

This is a reproducer disk image.  Download the attachment and
unpack it:

$ unxz fedora.img.xz
$ md5sum fedora.img

Now run old virt-inspector from RHEL 6.1 on it:

$ virt-inspector fedora.img

  Applications:

NOTE: "Error running rpm -qa" is NOT an error.  This is because this test
image is not a real VM disk image, it's just enough of a disk image to
demonstrate this bug.

What we are looking at here are the two warnings:

unknown filesystem label SWAP-lv1  (bug 666578)
unknown filesystem UUID dde7e2c... (this bug)

You can also try running new virt-inspector2 on the disk image, which
should just produce ordinary XML output with no warnings.  This is
because virt-inspector2 is the rewritten codebase which doesn't use the
old Perl inspection code.  The bug only exists in the old Perl inspection
code.
