We have upgraded a set of clusters from PVE6 to PVE8, and we have found that in newer kernels, OOM is a bit more 'aggressive' and sometime kill a VMs.
Nodes have plently of RAM (64GB, VMs are 2-3, each 8GB ram), VMs have qemu agent installed and ballooning enabled, but still sometime OOM happen. Clearly, if get OOM the main VMs that have the local DNS, we get some trouble. I've looked in PVE wiki, but found nothing. There's some way to relax OOM, or control their behaviour? In nodes there's no swap, so probably the best thing to do (but the hardest one ;-) is to setup some swap with a lower swappiness, but i'm seeking feedback. Thanks. -- _______________________________________________ pve-user mailing list pve-user@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user
