as ballooning is a lot more intrusive than ksm, I wonder if it couldn't be set to something like 90%. That sounds reasonable to me, but can you see that theoretical effect when you run your test? Hi Dietmar, Happy new year ! (I'm currently in holiday this week, so, I check that next week) I'll do more tests to be sure. (I don't use ballooning in production, but I'm a big user of ksm, I have some big nodes with something like 200GB ksm on 700GB servers). My Idea behind this is to implement auto-balancing, vm migration, when memory threshold is between ksm && autoballoonig). 1) 80%: ksm 2) ~= 85-89% : auto balancing/migration 3) ~= 90% : auto ballonning 4) ~= 100% : swap _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
