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.

I'm somewhat confused what the problem is here.  Can you describe
exactly what is the issue?

In any case, the original POD markup is correct:

=head1 EXAMPLE                                                                  
                                                                                
Follow F</var/log/messages> inside a virtual machine called C<mydomain>:        
                                                                                
 virt-tail -d mydomain /etc/fstab

Shouldn't the “/var/log/messages” be consistent with "/etc/fstab"?
The example is saying that follow the file : /var/log/mesages, but the command line you use /etc/fstab , I think that would confuse the user.
Comment 3 Richard W.M. Jones 2017-02-21 11:25:35 UTC 
/etc/fstab is in a verbatim section.

It all looks good in the HTML version:

http://libguestfs.org/virt-tail.1.html#example

I don't really think this is a bug.  It's just that the
text-based man page output doesn't have enough formatting
available to show verbatim sections in a different font.
Comment 4 Pino Toscano 2017-02-21 11:40:15 UTC 
Rich: the issue is that the man page says "see how you can monitor /var/log/messages", but the example for it (which follows) mentions /etc/fstab.
Comment 5 Richard W.M. Jones 2017-02-21 12:07:44 UTC 
Oh I see ...  yes, this is a bug, patch posted:

https://github.com/libguestfs/libguestfs/commit/2643c4d5f425b216d0d3fadee8f0f4ed69cfafba
Comment 7 Xianghua Chen 2017-03-28 06:18:27 UTC 
Verify with packages:
libguestfs-1.36.2-3.el7.x86_64

Steps:
1.
# man virt-tail
... ...
EXAMPLE
       Follow /var/log/messages inside a virtual machine called "mydomain":

        virt-tail -d mydomain /var/log/messages



So verified.
