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 of problem:
It's not possible to start installation from a virtual USB device on aarch64:

# virt-install --os-variant rhel8-unknown --arch aarch64 --disk /var/lib/libvirt/images/boot.iso,bus=usb --boot uefi --name test --memory 2048 --disk size=10 --graphics none

Starting install...

Version-Release number of selected component (if applicable):
qemu-kvm-4.2.0-51.module+el8.5.0+11141+9dff516f.aarch64
virt-install-2.2.1-4.el8.noarch

How reproducible:
Always on aarch64

Steps to Reproduce:
1. virt-install --os-variant rhel8-unknown --arch aarch64 --disk /var/lib/libvirt/images/boot.iso,bus=usb --boot uefi --name test --memory 2048 --disk size=10 --graphics none

Actual results:
ERROR    unsupported configuration: This QEMU doesn't support '-device usb-storage'

Expected results:
It's possible to start installation from a USB device
Comment 1 Andrew Jones 2021-06-15 09:29:41 UTC 
We don't support running AArch64 VMs without the AV version of qemu-kvm. If this use case is expected to work because it's commonly used by other architectures and/or is documented in the Virt user's guide, then please test again with the AV qemu-kvm to see if works there. If not, please move this BZ to that product.

That said, is this a regression? I.e. did this used to work with the non-AV version of qemu-kvm until recently?
Comment 2 Qunfang Zhang 2021-06-22 06:47:47 UTC 
Zhenyu re-tested RHEL-AV and RHEL 9 Beta, the issue is reproduced too. Filed Bug 1974579 to track RHEL-AV issue.

Thanks Qunfang and Zhenyu.

Jan, I'm closing this one as WONTFIX since as Drew explained in comment 1, we only fix bugs for the Advanced Virtualization stream.

Please, let's move this discussion to bug 1974579 (since AV is also affected).

Hello Drew,

I tested the qemu-kvm-4.2.0-48.module+el8.4.0 and qemu-kvm-4.2.0-29.module+el8.2.1 versions, 
They also don't support "usb-storage".
So I think this's not a regression.
And I tested on x86,PowerPC, they work fine.

I'd expect to compare against the same product for the other architectures, i.e. the output of -version here should be qemu-kvm-4.2.0-48.module+el8.4.0

Same comment as for x86.

OK, Testing, update results later.
