If I remember, some openvz features works only with cfq ? (ionice, openvz IO priorities)
Myself, I'm using deadline (because It's works better for my workload with my san), but I use kvm guests.

Objet: [pve-devel] default I/O scheduler - CFQ or Deadline?
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.
- only CFQ support priorities (ionice)
- 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!
