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.
