Proxmox 1.1 / KVM-83 and PCI Passthrough

[emigrating]

So I see that Proxmox 1.1 now uses KVM 83, however I am unable to find any instructions on how to do a PCI device passthrough to my Windows HVM's. Am I missing something, or is this still not supported in 1.1?

If it is supported, would someone please post a little step by step instruction for me? Thanks.

The hardware is VT-d capable and I'm already running with PCI Passthrough under Xen, but for various reasons I'm looking to move to KVM and Proxmox seems like a very nice alternative - but without HW passthrough it's a no go unfortunately.

Ok.

Second question, is it something that is being actively worked on and should be supported "soon"?

 

[dietmar]

kvm people are working on that, but AFAIK it depends on kernel 2.6.27 or newer, and we cant use that currently (no openvz support).

Yeah, I know it works under KVM - the question was more so is it something you guys (Proxmox) are working and will be supporting within the forseeable future.

 

[dietmar]

it depends on kernel 2.6.27 or newer, so we cant use it until openvz support 2.6.27, or kvm support 2.6.24.

2.6.28 will be better, but looks like openvz supports 2.6.27 now:

OpenVZ 2.6.27

Ok, so OpenVZ does now supports 2.6.27. What does this mean? Will you now implement this into the webUI so I can pass through a RAID controller to one guest and a CCTV capture card to another? If yes, do we have a timeline on this at all?

Where do you read that? They have just a first, unstable developement release.

I saw that Proxmox 1.2 was released. I was unable to find the changelog. Does the new version now support PCI passthrough in any form?

on each CD you find a release.txt.

also here: http://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_1.2

(pci passthrough is still not in as it needs a newer Kernel which we cannot user currently due to OpenVZ restrictions.)

Is the KVM web interface being worked on so that when the OpenVZ catches up the new KVM features are readily available?

I do not understand your question, can you describe it more detailed?

 

[Enigmus]

Sure thing. PCI passthru is available in KVM right now. The only reason it isn't in the Proxmox release is that OpenVZ doesn't support the kernel that the PCI passthru feature requires.

However, it would not be a problem for developemnt to break OpenVZ (in a test enviroment) in the interest of working on placing the PCI features into the Web interface. Will PCI passthrough options be available when OpenVZ finally catches up and supports the newer kernel?

There is an idea to have KVM only Proxmox VE version (additional) with the very latest Kernel and all KVM features - but currently we are too limited in resources but I assume end of this year pci pass through will work in some way with Proxmox VE.

Any updates on this or should I stop holding my breath?

no improvements yet. one question: do you need a tape drive inside KVM?

Does the new Proxmox VE Kernel (2.6.24-9) support PCI passthrough?

no, but you can test the new upcoming test kernel (2.6.32) - will be announced in this forum soon.
