Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.
Comment 5 zixchen 2021-07-02 01:11:25 UTC 
Version:
qemu-kvm-6.0.0-7.el9.x86_64
kernel-5.13.0-0.rc7.51.el9.x86_64

1. Check qemu-kvm-block-iscsi is disabled.
# rpm -qR qemu-kvm
qemu-kvm-block-curl = 17:6.0.0-7.el9
qemu-kvm-block-rbd = 17:6.0.0-7.el9
qemu-kvm-block-ssh = 17:6.0.0-7.el9
qemu-kvm-core = 17:6.0.0-7.el9
qemu-kvm-ui-opengl = 17:6.0.0-7.el9
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(PayloadIsZstd) <= 5.4.18-1

Actual and expected result: qemu-kvm-block-iscsi is disabled.

CCing Paolo Bonzini for future discussion and in case customers comment on this BZ requesting bringing back libiscsi.

Based on a separate conversation with Stefan and team, I'd like to note that Nutanix's AHV uses QEMU's iSCSI backend for certain types of disks. This is relevant because AHV's QEMU is a downstream from RHEL's QEMU. The concern is that if that's untested, there is risk that the code path could break and simply flipping it back on could not work (or even build). It would be good to understand the rationale for this change and, if it's indeed desirable to deprecate this part of QEMU (potentially even upstream), then whether we can discuss alternatives.
