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:
Boot guest with spice+qxl on rhel6.0 host and check the "info qtree" output, it's different with the output on rhel6.4 host with -M rhel6.0.0. Especially for the 'revision' property.
On rhel6.0 host:

Version-Release number of selected component (if applicable):
RHEL6.4 host:
kernel-2.6.32-348.el6.x86_64
qemu-kvm-0.12.1.2-2.348.el6.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Boot guest with spice and qxl on rhel6.0 host and check the "(qemu) info qtree" output for qxl part.
2. Repeat step 1 on rhel6.4 host with -M rhel6.0.0
3. Compare the output for qxl part.
Actual results:
"info qtree" output for qxl-vga does not match, pls check bug description above.
Expected results:
"info qtree" output for qxl-vga should match.
Additional info:
Verified the issue on qemu-kvm-rhev-0.12.1.2-2.376.el6.x86_64.
Check the qxl-vga info in "info qtree" output, the "vram_size" changes to 4096 and the revision changes to "1".

But boot a rhel6.4-64 guest, guest fails to start up the X windows. Can login guest via isa-serial console or ssh, but can not display the desktop correctly. Isa serial log and guest screenshot will be uploaded.
Hi, Gerd
Could you help confirm the following stuff:
(1) For this bug, the change is: the "vram_size" changes to 4096 and the revision changes to "1". Is it correct? And other properties do not change.
(2) Guest failed to boot up X Window after fix, does the patch have something wrong? Downgrade qemu-kvm to -355, guest X Window can display correctly.

Fedora 18's xorg segfaults when revision is 1. So I'd say no :/
