[pve-devel] RedHat KVM Performance Opt.

[Stefan Priebe]

Hi,

today i found this paper from redhat regarding performance optimizations 
for KVM.

As proxmox is based on the OpenVZ Kernel which is based on the RH 6 
Kernel it should match the stuff desribed here.

Can we perhaps rent some if the settings from here:
http://www.linux-kvm.org/wiki/images/5/59/Kvm-forum-2011-performance-improvements-optimizations-D.pdf

for example:
Activate Transparent Huge Pages (OpenVZ has it disabled since 042stab053.5)
vhost_net device should be default for network stuff
echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
libvirt xml: ... cache='none' io='native' per block device
