Can't change VLs directly in AC. I'd do a selection modifiier, clear VL and select books based on a template search virtual_libraries() (or a composite column using that). Then view action.

IIRC this one has been there since VL's was first added.

It's true that the universe within Calibre is vast.
Okay, Calibre opens from the virtual library, but what I was looking for through action chains was for the book viewer to open books from that virtual library.

No need for a template search. In the selection modifier, clear all VLs etc, search "vl:the_vl_name and formats:true", then select all books in view. The formats:true is there to filter out any books that don't have a format.

The attached chain shows how to do it. Change the name of the VL in the selection modifier to what you want.

A little module to re-calc the size column of a book.
Useful if you've had edited the book files by a third-party program.

import os

from calibre_plugins.action_chains.actions.base import ChainAction

class ReCalcSize(ChainAction):

    name = 'Re-calc Size'

    def run(self, gui, settings, chain):
        db = gui.current_db.new_api
        ids = chain.scope().get_book_ids()
        rslt = {}
        
        for book_id in ids:
            sizes = [0]
            for fmt in db.fields['formats'].for_book(book_id):
                path = db._format_abspath(book_id, fmt)
                sizes.append(os.path.getsize(path))
            max_size = max(sizes)
            if max_size != db.fields['size'].for_book(book_id):
                rslt[book_id] = max_size
        
        db.fields['size'].table.update_sizes(rslt)
        db.update_last_modified(rslt.keys())
