Comment 2 Peter Krempa 2023-07-19 11:45:10 UTC 
There was a recenlty fixed memory leak in virNodeDeviceGetXMLDesc:

https://bugzilla.redhat.com/show_bug.cgi?id=2208599

It reproduces with libvirt-8.0.0-5.9.module+el8.6.0+18552+b96c5a91.x86_64, which is the version mentioned above and is fixed in libvirt-8.0.0-5.10.module+el8.6.0+18949+ba4ca8a3.x86_64.

Can you please update and retry?
