Also I need to check how to allocated hugepage, when hostnodes is defined with
range like : "hostnodes:0-1".

Hi Wolfgang,
I just come back from holiday.

mmm indeed. I think this can be improved. I'll try to check that next week.

Currently we have the following code in hugepages_topology():
|for (my $i = 0; $i < $MAX_NUMA; $i++) {
|next if !$conf->{"numa$i"};
|my $numa = PVE::QemuServer::parse_numa($conf->{"numa$i"});
(...)
|$hugepages_topology->{$hugepages_size}->{$i} +=
hugepages_nr($numa_mem
