Hi Dmitriy

Thanks for the feedback. I have identified that debug is true in user_variable file and that too since very long time.

May be we have more debug logging in libvirtd after the wallaby upgrade.

So now below can be applied?

Change debug to False.

openstack-ansible os-nova-install.yml --tags nova-config

Regards

Hey,

Debug logs are only enabled if `debug: True` is set in user_variables or somewhere in group_vars:
https://opendev.org/openstack/openstack-ansible-os_nova/src/tag/wallaby-eom/templates/libvirtd.conf.j2#L3

With that default value of `debug` should be set to False.
You can try running smth like that to check value of the variable:
cd /opt/openstack-ansible; ansible -m debug -a var=debug nova_compute

Hi Team

I have recently done Victoria to Wallaby upgrade on my openstack-ansible installation.

After the upgrade we observe that  /var/log/libvirt/ size on all the computes was growing due to libvirtd.log file.

Further checking this file it can be seen that there are debug logs.

2025-01-19 11:15:20.817+0000: 2943565: debug : virNetlinkEventCallback:862 : dispatching to max 0 clients, called from event watch 7
2025-01-19 11:15:20.817+0000: 2943565: debug : virNetlinkEventCallback:876 : event not handled.
2025-01-19 11:15:20.821+0000: 2943605: debug : udevHandleOneDevice:1492 : udev action: 'add'
...

libvirtd configuration file on compute shows log_level=1

 cat libvirtd.conf
# Ansible managed

# enabling debug mode according to http://wiki.libvirt.org/page/DebugLogs
log_level = 1
log_filters="3:remote 4:event 3:json 3:rpc"
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
listen_tls = 0
listen_tcp = 0
unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
auth_tcp = "sasl"

No related parameter was changed/updated in user_variable file during the upgrade?

Any information what could have enabled the debug logs for libvirtd on all the computes?

Also how can I turn-off this using the openstack-ansible and what could be impact during the procedure?

Regards
