Additional info: but guest could run well when there are just one/two virtio-serial devices.
This bug only can be reproduced with q35 machine type.
And can reproduce this bug only with pcie-root-port device and without virtio-serial-device.

Hi Julia,
Would you please help to take a look at this?
Seems it is a Duplicate with the Bug 2001525 - [WRB][virtual network][qemu-6.1.50-1]Can not boot up guest with 14 devices via pcie-root-port
Thanks a lot in advance!
Best regards
Liu Nana
Also, there is one similar bug on RHEL9. Bug 2001630 - [WRB][virtual network][qemu-6.1.0-1]Can not boot up guest with 14 devices via pcie-root-port Please help to check this, thanks. Assigned to Amnon for initial triage per bz process and age of bug created or assigned to virt-maint without triage. Reproduced on rhel9 with SCSI-win8.1-32/64 guest. qemu-kvm-6.1.0-5.el9.x86_64 kernel-5.14.0-10.el9.x86_64 virtio-win-prewhql-0.1-214.iso seabios-bin-1.14.0-7.el9.noarc (In reply to ChenNana from comment #5) > Reproduced on rhel9 with SCSI-win8.1-32/64 guest. > > qemu-kvm-6.1.0-5.el9.x86_64 > kernel-5.14.0-10.el9.x86_64 > virtio-win-prewhql-0.1-214.iso > seabios-bin-1.14.0-7.el9.noarc This problem cannot be reproduced on ovmf, it is only reproduced on seabios *** This bug has been marked as a duplicate of bug 2001525 *** |
Description of problem: VM couldn't bootup successfully when test windows guest 'virtio_serial_file_transfer.unix_socket.boot_with_multiple_virtserialports.N_1.q35', there is "Guest has not initialized the display yet", looks like guest doesn't run normally, and the problem was hit on RHEL9/RHEL860 and guest's machine type was q35, Tests were passed on RHEL850 and guest's machine type were q35&pc.

connect VM via 'remote-viewer vnc://$IP:5900' Actual results: "Guest has not initialized the display yet" was there, guest couldn't run Expected results: enter into desktop and system runs well Additional info: I also did tests to rule out driver problems, run this case with previous virtio-win-prewhql rpm on those platforms, but the result was same, the case was failed on RHEL9/RHEL860 and passed on rhel850， so add a keyword 'regression'
