Hi Michael and all: Thank you for your comments and information.
In my case, the integrated GPU has only 128 mb and the external GPU has 2 GB ... There is a interesting difference between them. Although I can say that I can run into the VM all the programs that I've needed but I think they neither needed much memory of the GPU, at least I know with my little knowledge about this. I usually run GNU / Linux Operative Systems (In my host and in VM) About you said: "In theory we can already do it (see "PCI pass-through")", Would you please tell us where can I see it in the Web Site, Documentation: End - User Docs or Technical Docs ? Would you please tell us too, if there are changes programs code between VirtualBox 4.x and 5.x, because, without changes in my hardware host I can virtualize 64 bits O.S. in the firt (Actually I'm doing with Ubuntu 16.04 LTS), but in the second I can't (Not appear the options to virtulize 64 bits O.S.).
