good call to add this, there's some slight optimization potential though

I'd avoid `openvz` in newly added stuff, while we have it around in some places
it won't work anyway and we'll probably rip out most of that in a next major
release.

IIRC the 'type' is also in the VM list we get from PVE::Cluster::get_vmlist,
so we could just expand the `next` above, e.g.:

next if !$vmdata || (defined($param->{type}) && $param->{type} eq $vmdata->{type});

(untested)

we could guard the whole for loop that assembles storage stuff with a

if (!defined($param->{type}) || $param->{type} eq 'storage') {
   ...
}

to avoid doing work we don't use anyway.
