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the product is no longer active in Red Hat Bugzilla.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.
Description of problem:
qemu-kvm-rhev-2.1.2-1 couldn't support memory hot-plug with command:
(qemu)object_add memory-backend-ram,id=mem1,size=1G
(qemu)device_add pc-dimm,id=dimm1,memdev=mem1
then get error message as follows:
'DIMM property node has value 0' which exceeds the number of numa nodes: 0
Device 'pc-dimm' could not be initialized
But it is successful inside qemu-kvm-rhev-2.1.0-4
Version-Release number of selected component (if applicable):
inside host:
rpm -qa|grep qemu
qemu-kvm-rhev-2.1.2-1.el7.x86_64
uname -r
3.10.0-184.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.boot qemu with command:
/usr/libexec/qemu-kvm -name RHEL-Server-7.0-64 -m 4G,slots=4,maxmem=8G -smp 4,cores=2,threads=2,sockets=1,maxcpus=160 -monitor stdio
2.do memory hot-plug inside qemu:
(qemu)object_add memory-backend-ram,id=mem1,size=1G
(qemu)device_add pc-dimm,id=dimm1,memdev=mem1
Actual results:
wouldn't do memory hot-plug and get error message like this:
'DIMM property node has value 0' which exceeds the number of numa nodes: 0
Device 'pc-dimm' could not be initialized
Expected results:
do memory hot-plug successfully and there is no error message
