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.

Comment 13 Brian Lane 2016-05-26 21:46:36 UTC 
Have you tried this with a newer nightly? I also note that it look like this is actually a PXE boot with an updates.img. And was it an actual DVD build attached to the VM or just a boot.iso?
Comment 14 Jiri Konecny 2016-05-30 11:52:35 UTC 
I must apologize because this error is really badly described. From what I remember (I hope I remember it correctly) the problem happens only if I had DVD in my VM and did a PXE boot (without using this DVD, it was attached only) then this crash appeared.

I tested it on newest version of RHEL 7.3 and I can't reproduce it anymore. So I think it's already fixed by something else.

I'm closing this issue now.

Comment 16 Jiri Konecny 2016-07-26 09:50:21 UTC 
This issue still exists. I'm reopening this bug with better description from bug 1360228 

----------------
> Tried to do a PXE booted install with repositories on an DVD image mounted via > virtual DVD drive.
> Anaconda crashes upon reaching the Welcome screen.
> Looking at the program.log it looks like the ISO from the virtual DVD drive is > mounted once,

----------------

Thank you for reporting this Martin.
Comment 17 David Lehman 2016-07-31 22:59:11 UTC 
We mount the optical media, unmount it, then try to unmount it again. The second umount should not have been attempted because we should have been able to tell at that point that there was nothing to unmount.
