For transparent hugepage,

For 3.10 kernel it's enablde by default.
cat /sys/kernel/mm/transparent_hugepage/enabled
always] madvise never

for 2.6.32 kernel, I'm not sure, but I think that openvz have disabled them by default, don't remember exactly when

Hi, 

some news. 

It's seem that current proxmox qemu build don't have numa support enable. 

So, previous command line don't work. 


I'll send a patch for pve-qemu-kvm and also to add numa options to vm config 
file.

About the command line, each vm is a kvm process. 

So start your vm with current config, do a "ps -aux" , copy the big "kvm -id 
... " command line for your vm, 

stop the vm. 

then, 

add my specials lines about numa, 

and paste the command line to start the vm ! 


(kvm is so simple ;)
