If I remember, some openvz features works only with cfq ? (ionice, openvz IO priorities) see: http://pve.proxmox.com/pipermail/pve-devel/2012-March/002488.html
Myself, I'm using deadline (because It's works better for my workload with my san), but I use kvm guests. ----- Mail original ----- De: "Martin Maurer" <mar...@proxmox.com> À: pve-devel@pve.proxmox.com Envoyé: Lundi 6 Mai 2013 14:21:54 Objet: [pve-devel] default I/O scheduler - CFQ or Deadline? Hi all, We want to discuss the changing of the pve default I/O scheduler from CFQ to Deadline. I want to collect feedback, pros and cons here. CFQ: - only CFQ support priorities (ionice) Deadline: - No support for priorities but generally faster for KVM in some (or a lot of?) systems. The scheduler can always be changed manually if the default is not suited (e.g. in /etc/default/grub). What do you think about this? Please report your thoughts!
