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.

sga device has been removed on qemu-kvm-6.0.0-13.el9_b.1, according to Comment 3, we need to enable it, right?

Nope, this is about forwarding change from qemu-kvm-6.0.0-13.el9_b.1 to qemu-kvm-6.1.0-* builds (from 9-Beta to 9.0.0). You can see sga device present in qemu-kvm-6.1.0-1.el9.

Tested with qemu-kvm-6.1.0-2.el9, sga device has been re-enabled. Thanks.

Run the command "-device sga" with qemu-kvm-6.1.0-2.el9, hit the following issue, but not hit it on qemu-kvm-6.1.0-1.el9.

seabios-1.14.0-7.el9.x86_64

run it with qemu-kvm-6.1.0-2.el9:
# /usr/libexec/qemu-kvm -device sga
Could not open option rom 'sgabios.bin': No such file or directory

run it with qemu-kvm-6.1.0-1.el9:

Hi Miroslav,

Could you please help check it? Many thanks.
Comment 13 Richard W.M. Jones 2021-09-17 07:14:39 UTC 
This bug is the RHEL 9 (not Beta) bug, and we want to remove SGA in
this version.

Hi Richard,

According to Comment 7 and Comment 12, sga device is not removed in qemu-kvm-6.1.0-2.el9. If we indeed remove it, the bug should be failed on_qa, right?

I see the bug was reported against RHEL 9, and we re-enable sga device on RHEL 9 beta. (Tracked by Bug 2002993 - [RHEL 9 Beta] Reenable SGA device)

It is a little confused for the Comment 3, if we remove sga device, how to use libguestfs tool. Please help explanation, many thanks.

Sorry, I see the bug, Bug 2002325 - Use -machine graphics=off instead of sga device, libguestfs should work well with it.

Just one concern: According to Comment 7 and Comment 12, sga device is not removed in qemu-kvm-6.1.0-2.el9. If we indeed remove it, the bug should be failed on_qa, right?
Comment 16 Miroslav Rezanina 2021-09-17 09:45:57 UTC 
This BZ failed qa as there's missing patch for disabling sga device that wasn't part of MR. Need to be added to be fixed.
Comment 17 Richard W.M. Jones 2021-09-17 09:54:08 UTC 
For RHEL 9 GA: libguestfs now uses -machine graphics=off, and libvirt
will be similarly modified (although that's not upstream yet).  SGA
should be removed from qemu-kvm.

For RHEL 9 BETA: we need to enable SGA, tracked in bug 2002993.
Comment 18 Xueqiang Wei 2021-09-18 01:44:23 UTC 
Hi Richard and Miroslav,

Many thanks. According to your comments, re-assign it. If I was wrong, please correct me. Thanks again.
