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.

Fixed In Version: qemu-kvm-rhev-2.8.0-1.el7
Doc Type: Bug Fix
Doc Text:
Using "Opteron" CPU options with Red Hat Enterprise Linux (RHEL) 6 machine types caused the QEMU emulator to terminate unexpectedly due to a typographical error in one of device names. This update corrects the error so "Opteron" CPU options can be used with RHEL 6 machine types as expected.

Description Paolo Bonzini 2016-12-15 16:31:54 UTC 
Starting QEMU with "-cpu Opteron_G4" gives the following error:


Unexpected error in object_property_find() at qom/object.c:1003:
2016-12-15T13:58:43.140073Z qemu-kvm: can't apply global
Opteron_G4-x86_64-cpu.x1apic=off: Property '.x1apic' not found


This is due to a rebase typo.
Comment 2 Paolo Bonzini 2016-12-15 16:53:44 UTC 
There is an imprecision in comment 0.  You need "-cpu Opteron_G4 -M rhel6.6.0" to trigger the bug.
Comment 4 Paolo Bonzini 2016-12-15 17:44:09 UTC 
Proposing for z-stream because it's a regression that causes a crash on startup after upgrading from 7.2 to 7.3.  It's been already reported on CentOS by oVirt hosted engine users.  The fix is one line (one byte really), so it's safe.
Comment 6 Guo, Zhiyi 2017-01-05 09:09:14 UTC 
Reproduce this issue against qemu-kvm-rhev-2.6.0-28.el7_3.2.x86_64.
