1224542 – unsupported devices need to be disabled in qemu-kvm-rhev after rebasing to 2.3.0

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 Xiaoqing Wei 2015-05-24 10:47:51 UTC

Description of problem:

unsupported devices need to be disabled in qemu-kvm-rhev after rebasing to 2.3.0

eg:

piix3-ide, piix3-ide-xen, piix4-ide, via-ide
i8042, isa-fdc
etc

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.3.0-1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.
qemu-kvm -device \? 2>&1 | grep -i xen
name "piix3-ide-xen", bus PCI

2.
3.

Actual results:
devices above are displayed when querying qemu

Expected results:
should not appear when querying

Additional info:

this should be caused by rhel-only patches lost after rebase to 2.3.0

a series of 17 patches, existed in old version.
forward-porting should fixing.

782eba1 rhel: Revert unwanted cannot_instantiate_with_device_add_yet changes

Comment 1 Xiaoqing Wei 2015-05-24 10:50:10 UTC

since this is introduced after rebase, adding Regression keyword.

Comment 2 Xiaoqing Wei 2015-05-24 10:52:07 UTC

(In reply to Xiaoqing Wei from comment #2)
> adding RH-Author: Kevin Wolf <kwolf>

This is really Markus' series. I only fixed a bug and resent the series because
he was on PTO back then. I think Markus is still the right assignee for this, so
I'm reassigning this BZ to him.

Comment 7 Miroslav Rezanina 2015-09-02 14:16:05 UTC

Fixes for added devices  was introduced in qemu-kvm-rhev-2.3.0-10.el7

Comment 10 Qian Guo 2015-09-10 06:51:16 UTC

Hi, Markus

Seams the "device" the comment 0 mentioned is still in the device list with latest qemu-kvm-rhev 2.3.0 build:

# rpm -q qemu-kvm-rhev
qemu-kvm-rhev-2.3.0-22.el7.x86_64

# /usr/libexec/qemu-kvm -device \? 2>&1 | grep -i xen
name "piix3-ide-xen", bus PCI

So I will first re assign this bug  since the device is still in the device list.

Comment 12 Markus Armbruster 2015-09-18 13:46:14 UTC

Looks like most of commit 782eba12 didn't make it through the rebase.

Mirek volunteered to take care of this, reassigning.
