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.

Xinerama does not work on 6.2. This may be a bug in xorg-x11-drv-qxl, in qemu, or in spice-server.

Some initial investigation:
- The spice client crashes when the server first asks for four screens.
Starting spicec again makes it display the four windows and run without
crashing.
- There are two relatively straightforward fixes to the X driver, both having
to do with the extra devices not emulating VGA.
- The PCI probing skips non-VGA devices
- The "save state" routine saves the state of the VGA fonts. When
that is called for non-VGA hardware it gets applied to the one
VGA device, putting it into VGA mode which then creates chaos.
- With those fixes, the X server will start in Xinerama mode, but there is
something wrong with the tablet; it seems to be stuck on the third screen.
Running without the tablet then seems to work.

Created attachment 519304[details]
xorg.conf file with a Xinerama setup
QA, I'll attach an xorg.conf file that works for me, although it may be that you will need to adjust the PCI IDs according according to how your specific VM is set up. You can find the devices by doing
lspci -v
as root and looking for QXL devices.
