Hello,

After doing more research, it appears that the use of the -smp 96 option 
without any other precision creates a VM with one core and 96 sockets.

When using the option --smp cores=96 the VM is created with 96 cores and 
one socket and the 4.19.0-13 boots correctly.

So the addition of MAXSMP is not required to have a VM correctly started 
with more than 64 cpus.

Thanks for you attention,

Kind regards,

...Louis
