You can achieve this using HostDatastorBrowser but to filter the unregistered Virtual Machines you have to compare the vmx files returned with the vmx files of Virtual Machines available in Datastore.
Please refer below code snippet
my $host_data_browser = Vim::get_view(mo_ref => $datastore->browser);
my $datastore_mor = $host_data_browser;
my $ds_mor = $datastore;
my $path = '';
my $level = 0;
my $browse_task;
my $vm_array = Vim::get_views (mo_ref_array => $ds_mor->vm) ;
my @vms;
my $match = ;
foreach my $vm (@$vm_array){
push @vms, $vm->config->files->vmPathName;
}
my $files = FileQueryFlags->new(fileSize => 1,
fileType => 1,
modification => 1
);
my $hostdb_search_spec = HostDatastoreBrowserSearchSpec->new(
matchPattern => $match,
details => $files);
eval {
$browse_task = $datastore_mor->SearchDatastoreSubFolders(datastorePath=>$path,
searchSpec=>$hostdb_search_spec
);
};
if ($@)
elsif (ref($@->detail) eq 'InvalidDatastore')
else
}
else
}
my $vmxpath;
foreach (@$browse_task) {
my $found = 0;
if(defined $_->file) {
my $y = $_->folderPath;
foreach my $x (@{$_->file}) {
foreach my $vmx (@vms){
$vmxpath = $x->path;
my $path = $y."/".$x->path;
if($path eq $vmx){
$found = 1;
}
}
}
if( $found eq 0 && $vmxpath){
print "\n".$vmxpath." not registered.";
}
}
}
