Description Charles Barto 2021-11-26 16:50:19 UTC
Description of problem:
I attempted to start a libvirt VM with the <vcpu placement="auto" /> configuration.
SELinux is preventing numad from using the 'ipc_owner' capabilities.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that numad should have the ipc_owner capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'numad' --raw | audit2allow -M my-numad
# semodule -X 300 -i my-numad.pp
