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 Luyao Huang 2015-07-20 08:49:45 UTC 
Description of problem:
guest cannot start when set numatune and disable cpuset in qemu.conf

Version-Release number of selected component (if applicable):
libvirt-1.2.17-2.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. disable cpuset in qemu.conf:

# vim /etc/libvirt/qemu.conf
cgroup_controllers = [ "devices", "blkio", "cpu", "cpuacct", "memory"]


2. restart libvirtd:
# service libvirtd restart
Redirecting to /bin/systemctl restart  libvirtd.service


3. prepare a guest with numa settings:
# virsh numatune rhel7.0
numa_mode      : strict
numa_nodeset   : 0

# virsh start rhel7.0
error: Failed to start domain rhel7.0
error: internal error: Controller 'cpuset' is not mounted


Actual results:
guest cannot start when set numatune and disable cpuset in qemu.conf


Expected results:
guest can start success since the libnuma have some function for bind to a node , and we need check if cpuset is disabled then try to use it.

Additional info:

Also found this issue with setvcpus and iothreadadd:

# virsh setvcpus test4 3
error: internal error: Controller 'cpuset' is not mounted

# virsh iothreadadd test4 11
error: Requested operation is not valid: failed to set cpuset.cpus in cgroup for id 11

Verify it as follows. The result is expected. Move its status to VERIFIED.

# rpm -q libvirt

# cat /etc/libvirt/qemu.conf|grep cgroup_controllers
cgroup_controllers = [ "cpu", "devices", "memory", "blkio", "cpuacct" ]


# service libvirtd restart
Redirecting to /bin/systemctl restart  libvirtd.service


# virsh start test4
