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.	Story Points:	---

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.
qemu cmds used:
/usr/libexec/qemu-kvm -name rhel7.2 -m 2048 \
	-cpu Opteron_G4 -M rhel6.6.0 \
	-smp 4 \
	 -vga qxl\
	-spice port=3001,disable-ticketing \
        -device virtio-serial -chardev spicevmc,id=vdagent,debug=0,name=vdagent \
	-serial unix:/tmp/m,server,nowait \
        -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
	-drive file=rhel73,if=none,id=drive-scsi-disk0,format=qcow2,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,id=scsi0 -device scsi-hd,drive=drive-scsi-disk0,bus=scsi0.0,scsi-id=0,lun=0,id=scsi-disk0,bootindex=1 \
	-monitor stdio \
Steps:
1.Install rhel7.3 guest use above cmd.
