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 of problem:
Spice console is frozen after GRUB2 command 'set gfxpayload=keep'. This command is used by default in yesterday's RHEL 7 nightly build.

spice-gtk-0.11-11.el6_3.1.x86_64

How reproducible:
100 %


Steps to Reproduce:
1. Install some VM with GRUB2 (e.g. yesterday's RHEL 7-nightly)
2. Boot VM up
3. Open a SPICE console
  

Actual results:
Console is frozen, last message is in attached image.


Expected results:
Console works :-)


Additional info:
I can provide access to problematic VM in our Brno lab.

Created attachment 691468 [details]
screenshot of frozen SPICE console

Created attachment 691476 [details]
relevant configuration files from /boot

Created attachment 691477 [details]
complete file list from /boot

Note: Machine boots up normally, networking is functional, I can SSH in without any problem (if I guess IP address :-)). Only the console is broken.

Command for quick fix of GRUB's configuration:
sed --in-place=.orig '/gfx/d' /boot/grub2/grub.cfg

This removes all lines containing "gfx", so GRUB2 will use normal text mode and SPICE will work.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

I've tried to reproduce this today, and for me things work fine.

I believe this is a known and since the original report has been filed, fixed, vgabios issue. It is fixed by this errata: http://rhn.redhat.com/errata/RHBA-2013-0487.html
