2.Guest can not boot up, VNC show info: Guest has not initialized the display (yet)

Actual results:
Guest can not boot up, VNC show info: Guest has not initialized the display (yet)

Expected results:
Guest works well

Additional info:
1. qemu-kvm-6.0.0-29.module+el8.5.0+12386+43574bac.x86_64 test pass, so add keywords "Regression"
2. RHEL.8.5.0 guest hit same issue.

This issue is not reproduced on rhel9-beta

Test Version:
qemu-kvm-6.0.0-13.el9_b.1.x86_64
kernel-5.14.0-1.el9.x86_64

Hi Lei,

I see you report this bz with QEMU 6.1, so the test with qemu-kvm-6.0 on rhel9-beta is not meaningful i think.
The meaningful way is to use the weeklyrebase build for RHEL9:
http://batcave.lab.eng.brq.redhat.com/repos/test/RHEL-9/WRB/latest/

(By the way, the weeklyrebase build for this week have not come out)

Hi Yanan

Thanks for your update. I tried use qemu package "qemu-kvm-6.1.0-1.el9.x86_64" reproduced this bug, so clone it to rhel9. When the latest weekly packages comes out, I will test again.

Thanks
Lei
