Feature Request: Support for PCI Passthrough Devices

[dcode]

Terraform Version

0.11.13

vSphere Provider Version

1.11.0

Affected Resource(s)

(probably)

• vsphere_virtual_machine
• vsphere_host
• vsphere_host_pcipassthru (proposed new resource)

Terraform Configuration Files

N/A

Debug Output

Expected Behavior

Ability to associate a PCI device ID (which is a host resource) to a VM as a PCI passthrough object. This has to happen prior to power on. It also requires reserving all the VM memory.

Actual Behavior

After I run terraform apply I have to shutdown the VM and manually add the PCI device in vCenter.

Steps to Reproduce

Try to find in the documentation how to do a PCI passthrough in the vsphere provider and feel sad when you realize it doesn't exist.

Important Factoids

Obviously this isn't a super common use case, but it's something I need. In my case, I'm passing through a hardware NIC due to latency/performance reasons. The OpenStack provider features (linked in references) was developed for this same use case: latency.

[dcode]

Additional note, it would be handy to be able to do a lookup on (vendor_id and device_id) OR system_id. Which is to say, lookup attributes of any available device of a specific device type (e.g. Intel X710 NIC, or nvidia GPU) or just select based on the bus address. This is what inherently happens in openstack because you associate a device whitelist with a vm flavor.

@dcode Is there any update on this enhancement as to when will this be implemented?
Do you have any workaround as to how to add PCI device to VM through Terraform?

[dcode]

@sumitmaggo, I don't have a work around short of powering off the VM and adding it manually. I'm not a terraform developer. I filed this because I need this functionality.

working on some new stuff with GRID gpus - PCI support would be greatly appreciated.

This would be very useful indeed, hope it can be added soon.
