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.

Additional info:
Comment 1 yalzhang@redhat.com 2023-01-05 02:18:10 UTC 
It should be the same issue with bug 2154750.
Comment 2 liting 2023-01-06 03:30:02 UTC 
RHEL-9.2.0-20221224.0 also has this issue

Comment 3 yalzhang@redhat.com 2023-01-06 06:10:45 UTC 
Actually, this issue occurs since qemu-kvm-7.2.0-1.el9.x86_64

1. test on qemu-kvm-7.1.0:
# rpm -q qemu-kvm libvirt
qemu-kvm-7.1.0-7.el9.x86_64
libvirt-8.10.0-2.el9.x86_64

Set vm with xml includes:
<cputune>
    <emulatorpin cpuset='1'/>
  </cputune>
  <numatune>
    <memory mode='strict' nodeset='0'/>
  </numatune>
(host cpu 1 belongs to host node 1, not host node 0)

the related qemu cmdline:
-object '{"qom-type":"memory-backend-ram","id":"pc.ram","size":2147483648,"host-nodes":[0],"policy":"bind"}' \

2. Update to qemu-kvm-7.2.0-1.el9.x86_64, vm start failed with the same setting
# rpm -q libvirt  qemu-kvm
libvirt-8.10.0-2.el9.x86_64
qemu-kvm-7.2.0-1.el9.x86_64

# virsh start rhel 
error: Failed to start domain 'rhel'
error: internal error: process exited while connecting to monitor: 2023-01-06T06:05:25.568613Z qemu-kvm: Setting CPU affinity failed: Invalid argument

3. Update the setting to be:
<cputune>
    <emulatorpin cpuset='2'/>
  </cputune>
  <numatune>
    <memory mode='strict' nodeset='0'/>
  </numatune>
(host cpu 2 belongs to host node 0)

# virsh start rhel 
Domain 'rhel' started

related qemu cmdline:
-object '{"qom-type":"thread-context","id":"tc-pc.ram","node-affinity":[0]}' \
-object '{"qom-type":"memory-backend-ram","id":"pc.ram","size":2147483648,"host-nodes":[0],"policy":"bind","prealloc-context":"tc-pc.ram"}' \
