[pve-devel] unknown setting 'maxcpus'

[Alexandre DERUMIER]

maxcpus is computed now from sockets * cores.

qemu team have done change in code, because for example 
it was possible to do  sockets=1, cores=2, maxcpus=4.

which is wrong.

sockets and cores define the cpu topology.

vcpus defined the number of enabled cores




previously, proxmox was doing

if($maxcpus){
 push @$cmd, '-smp', "cpus=$cores,maxcpus=$maxcpus";

with socket always =1

Now, It's

push @$cmd, '-smp', "$vcpus,sockets=$sockets,cores=$cores,maxcpus=$maxcpus";
with $maxcpus = $cores*sockets


To translate
if you had

cores:4
maxcpus:8


if should be translate with:

cores:8
vcpus:4

So i need to sed maxcpus: to vcpus: ? 

Do i need todo this only for the current running machine or also for old 
snapshots.
