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 Yihuang Yu 2022-12-18 07:03:34 UTC 
Description of problem:
In downstream qemu-kvm, ipxe-roms-qemu is not a dependent pkg on aarch64, the qemu process can be started with an empty romfile in the past, but failed with qemu-kvm-7.2.0-1.el9

Version-Release number of selected component (if applicable):
QEMU version: qemu-kvm-7.2.0-1.el9.aarch64
# rpm -qa | grep qemu
qemu-kvm-common-7.2.0-1.el9.aarch64

qemu-kvm-7.2.0-1.el9.aarch64

How reproducible:
always

Steps to Reproduce:
1. Reproducer 1:
# /usr/libexec/qemu-kvm -M virt -cpu host
qemu-kvm: failed to find romfile "efi-virtio.rom"

2. Reproducer 2:
# /usr/libexec/qemu-kvm -M virt -cpu host -nodefaults -device pcie-root-port,id=pcie-port.1,bus=pcie.0,addr=0x2 -monitor stdio
QEMU 7.2.0 monitor - type 'help' for more information

(qemu) netdev_add tap,id=net1
(qemu) device_add virtio-net-pci,id=nic1,netdev=net1,bus=pcie-port.1,addr=0x0

Actual results:
Error: failed to find romfile "efi-virtio.rom"

Expected results:
Can create virtio-net-pci device without efi-virtio.rom

This blocks all tests of virt-rhel9.2.0, so add TestBlocker.
Comment 4 lijin 2022-12-19 05:52:24 UTC 
Hi Alexander,

This issue blocks all testings for qemu7.2, could you assign this bz and see if we can have a quick fix?

Thanks.
Comment 5 Yihuang Yu 2022-12-19 05:57:07 UTC 
Actually, I don't think this is a real test blocker, we can install ipxe-roms-qemu to provide efi-virtio.rom, or set "rombar=0" property in the virtio-net-pci device, then qemu process can be started, although it will still prompt that the "efi-virtio.rom" file cannot be found(the file will not be used). So I can see all the tests of my auto job pass.

Remove testblocker keyword and adjust priority based on comment#5.

And since this is not a test blocker any more.  
It's not so urgent, take your time, Alexander.
