@MJGZ51 Hi!
Since 8.3 PCI passthrough is part of the XAPI and come with dedicated xe commands:
xe pci-list to have the list of PCI devices and then:
xe pci-disable-dom0-access uuid=<pci uuid> to hide th device from dom0xe pci-enable-dom0-access uuid=<pci uuid> to unhide the from dom0These are the same API calls made by XO or any XAPI clients 
No need to edit manually the cmdline anymore!

I asked because languages like PHP and Ruby are very popular in the web and have many developers.
Javascript and node.js seem to be more popular than PHP and Ruby:
