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.

How reproducible:
100% on the same ppc host, while not on the other one

Steps to Reproduce:
1. Check the host numa status:

2. Start a guest in qemu:
/usr/libexec/qemu-kvm -name spaprqcow-0507 -S -machine pseries-rhel7.1.0,accel=kvm,usb=off -m 129708 -realtime mlock=off -smp 4,sockets=1,cores=4,threads=1 -numa node,nodeid=0,cpus=0,mem=32427 -numa node,nodeid=1,cpus=1,mem=32427 -numa node,nodeid=2,cpus=2,mem=32427 -numa node,nodeid=3,cpus=3,mem=32427 ...

3. Check the qemu-kvm related numa node status with cmd 'numastat qemu-kvm'/'numastat -c qemu-kvm':
[root@ibm-p8-kvm-02-qe ngu]# numastat -c qemu-kvm

Actual results:
Aborted (core dumped) as above.

Expected results:
The cmd could be executed without any problem.

Additional info:
Ever met the problem when the same host was installed with BE OS and following sw versions previously:
Host kernel: 3.10.0-234.el7.ppc64
Qemu-kvm-rhev: qemu-kvm-rhev-2.2.0-8.el7.ppc64

Comment 3 Min Deng 2017-04-19 07:04:54 UTC 
It still could be reproduced on the following builds
numactl-2.0.9-6.el7_2.ppc64le
