Do You see similar results at Your side? Best regards Would you mind to share you argument set to an emulator? As far as I understood you are using plain ballooning with most results from above for which those numbers are expected. The case with 5+gig memory consumption for deflated 1G guest

Hi Daniel, would it possible to adopt an optional tunable for a virCgroup mechanism which targets to a disablement of a nested (per-thread) cgroup creation? Those are bringing visible overhead for many-threaded guest workloads, almost 5% in non-congested host CPU state, primarily because the host
