[pve-devel] Error in PVE with win2008r2 and 256GB RAM

It should work on top of proxmox 3.3 (Don't have tested).

To be sure, make a copy of your current deb (/var/cache/apt/archives) , if you want to rollback later.

Well, just test if you observe your previous performance problems.

Maybe a memory benchmark could provide some interesting results. (not sure which tools is best for this on windows)

Hi Alexandre 

OOOooo ...Many thanks for do the patches!!!!, 
...I will be installing. 

Moreover, i would like to tell you two things: 
1) I have these packages installed in my two servers (configured in HA and 
both are equals in software and hardware) 
pveversion -v 
proxmox-ve-2.6.32: 3.3-139 (running kernel: 3.10.0-5-pve) 
pve-manager: 3.3-5 (running version: 3.3-5/bfebec03) 
pve-kernel-3.10.0-5-pve: 3.10.0-19 
lvm2: 2.02.98-pve4 
clvm: 2.02.98-pve4 
corosync-pve: 1.4.7-1 
openais-pve: 1.1.4-3

Hi, 
can you test this: 

http://odisoweb1.odiso.net/pve-qemu-kvm_2.2-2_amd64.deb 
http://odisoweb1.odiso.net/qemu-server_3.3-5_amd64.deb 


then edit your vm config file: 


sockets: 2 
cores: 4 
memory: 262144 
numa0: memory=131072,policy=bind 
numa1: memory=131072,policy=bind 


(you need 1 numa by socket, total numa memory must be equal to vm memory). 

you can change cores number if you want. 


and start the vm ?

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 ;)
