Here is a status from another host: domid=0: nr_frames=4, max_nr_frames=256 domid=487: nr_frames=6, max_nr_frames=256 domid=488: nr_frames=5, max_nr_frames=256 domid=489: nr_frames=4, max_nr_frames=256 domid=490: nr_frames=6, max_nr_frames=256 domid=491: nr_frames=7, max_nr_frames=256 domid=492: nr_frames=4, max_nr_frames=256 domid=493: nr_frames=4, max_nr_frames=256 domid=494: nr_frames=29, max_nr_frames=256 domid=495: nr_frames=4, max_nr_frames=256 domid=496: nr_frames=4, max_nr_frames=256 domid=497: nr_frames=5, max_nr_frames=256 domid=498: nr_frames=4, max_nr_frames=256 domid=499: nr_frames=4, max_nr_frames=256 domid=500: nr_frames=4, max_nr_frames=256 domid=501: nr_frames=4, max_nr_frames=256 domid=503: nr_frames=5, max_nr_frames=256 domid=572: nr_frames=13, max_nr_frames=256 domid=575: nr_frames=7, max_nr_frames=256 Most of the hosts have older kernels and nr_frames < 10. And than 494 has a stretch kernel and only 4 vcpus but is quite close to the current default of 32. Maybe it just depends on the amount of disk IO? -- Valentin
