The scope name, even according to our docs is "machine-$DRIVER\x2d$VMNAME.scope" virSystemdMakeScopeName would use the resource partition name instead of "machine-" if it was specified thus creating invalid scope paths. This makes libvirt drop cgroups for a VM that uses custom resource partition upon reconnecting since the detected scope name would not match the expected name generated by virSystemdMakeScopeName. The error is exposed by the following log entry: debug : virCgroupValidateMachineGroup:302 : Name 'machine-qemu\x2dtestvm.scope' for controller 'cpu' does not match 'testvm', 'testvm.libvirt-qemu' or 'machine-test-qemu\x2dtestvm.scope' for a "/machine/test" resource and "testvm" vm.
