The "Use my ESXi host for multiple HTPC's using passtrough" project

This is pretty interesting to hear, I have a setup with a virtual HTPC and a bunch of other VM's for a home lab I've got going on, but I use separate USB controllers for the VM's I need hardware access to. I use an AMD R5 230 (HD6450 essentially) passed through and have no issues at all.

I rolled my own ESXi ISO by using the powershell script from v-front: http://www.v-front.de/p/esxi-customizer-ps.html

Should download the latest build including the correct patch (I've checked, mine is 3380124, same as update 1b released January 7th), and you can update from the repo's there to get access to the 'esx-ui' web based management tool, avoiding using the java appliance all the time, most updated cpu-microcode and support for non-native/HCL sata controllers.

Hmm..

Maybe all is not lost after all...

Do you know if this will work with just the hypervisor?

I'd hate to roll my own ISO, upgrade my hypervisor, and then have the license not work anymore...
 
You should just be able to upgrade from the esxi cli. Enable ssh within vsphere then you can update the hypervisor from the cli.

Yeah, I tried that based on the guide here, but I wound up with an error message no one else on there seems to be getting:

Code:

Please refer to the log file for more details.

So I did some poking aropund in the logs, and this was the most detail I was able to find:

So this was good info.

I was able to get the Update 1b ISO like this. Now I just need to figure out how to to the update.

I'll probably wind up DD:ing an image of my boot drive just in case, so that if I run the update, and suddenly it thinks it is a full fledged vpshere install, and my key ceases to work, I can revert.
 
Your best bet might be just installing to a new flash drive and importing your datastores and VM's to the new software stack prior to applying your license.

I get away with the free licensed version of ESXi 6 as I've only got 1 CPU socket, similarly I also fall within the parameters of a free licensed version of ESXi 5.5 as I'm capped at 32GB RAM due to my platform.

You will require licensing for either version as you've got greater than 1 CPU socket and greater than 32GB RAM.

I can't however think of any reason why whatever license you're using now, so long as it allows you access to the hardware you have listed wouldn't work on the updated base image profile for 6.0 U1b

Well, honestly I'm confused about their different product lines.

I'm running a single standalone hypervisor, and that's all my license works on. It would not work on a Vsphere installation, only Vsphere Hypervisor. It is a free license I've just been reusing since I originally installed ESXi 5.0

It doesn't seem to limit me on the sockets or on the RAM (I have two sockets, 6 cores with hyperthreading each, and 96GB of RAM). Maybe I'm grandfathered in somehow?

The truth is, I find VMWares different products more confusing than any product lineup of any other company I have ever seen, and their disaster of a confusing mess of a website doesn't really help either.
 
Yeah, they generally expect to have someone on their end doing the licensing for you.
 
The 32GB limit for free tier was removed with one of the 5.5 versions. IIRC, u1 in 2013.

I had to get a new free license for 6.0. Haven't run into any related issues so far, but it's on an E3 with 24GB, so...
 
Hi, I know this threads been dead for a while, but I am at the point of wanting to do exactly this. I have been using an i5 Desktop with Linux running TVHeadend and Kodi, then Odroids (Like Pi's) in the kitchen, bedroom, etc. I use Vsphere and VM's in my work, so am now at the stage where I would like to combine the lot into one main Server, using ESXi and passthrough to multiple graphics cards. I would like some advice on a good 'budget' setup (Motherboard and Xeon CPU's), nothing new, good and cheap. Any advice would be very welcome please.

Regards.
 
Well, I was never really able to make this work properly, either with ESXi or Proxmox. I eventually abandoned this project in favor of individual HTPC's in each room. My problem was that I needed Nvidia support, and it is much trickier to get Nvidia passthrough working than it is with AMD GPU's.

My system was a great bang for the buck with older Westmere-EP Xeons and a new old stock Supermicro X8DTE motherboard on eBay, but I picked that up in the summer of 2014, so it's getting a bit old and slow by modern standards.

I'm sure others here, or in the Virtualization subforum can help with recommendations of what the current bang for the buck setup might be.
 
Hi Zarathustra[H], thanks for your reply. I'm hoping things have changed over the past year and more Nvidia cards are cpabale of passthrough (or just wishfull thinking). How can I tell if an Nvidia card is capable of passthrough?
 
Hi Zarathustra[H], thanks for your reply. I'm hoping things have changed over the past year and more Nvidia cards are cpabale of passthrough (or just wishfull thinking). How can I tell if an Nvidia card is capable of passthrough?

My understanding is that it simply can not be done in ESXi due to Nvidia blocking it in their driver. If they discover they are passed through, the driver refused to work.

Nvidia wants to sell expensive professional GPU's for passthrough purposes.

If - however - you go with KVM and some other third party hypervisors, there are workarounds, but nothing that is guaranteed to work. You need to doit in UEFI mode, which isn't always fully supported in the bios of the system or the firmware ofthe GPU, so it may be on a Case by case basis.

Try googling for Nvidia passthrough and UEFI and limit your search time wise to the last year or two and see what you can find. Things may have changed since I did it.
 
You can passthrough Nvidia GPUs now. You need to add an additional parameter to the VMX file that effectively hides the hypervisor from the guest OS. Then, Nvidia drivers will work.

Hi metril, that's excellent news. Do you know of a good tutorial on how to do this please?

Just coming back to this one, as i recently tried to run an AMD 380 under ESXi 6.5 but get ESXi rebooting, similar to this person's issue.
https://communities.vmware.com/thread/549146

Sounds like the same pass-off issue you noted which some internet folk noted only went away if they went all the way back to 5.5
 
I have just tried this with ESXi 6.5, Nvidia GT710 on Ubuntu 16.04, but as soon as I intall the Nvidia drivers and reboot, I get to the login screen and get stuck there, login in just returns me to the login screen, unable to login.
Any ideas please?

No ideas - I don't passthrough GPUs anymore because I found its usefulness limited compared to even cheap GPUs on workstations.

One way to test if it is ESXi or Ubuntu is to try to create a Windows VM and see if it uses the nVidia GPU correctly. If it fails it's ESXi acting up, otherwise it's Ubuntu.

Some motherboards are more sensitive to passthrough than others - what are you using?

I can say that I've been attempting GPU pass through on and off for more than 5 years and I've not seen a stable system yet. If I had to guess the people who are getting this working, are spending a lot of time tweaking things. Years ago it used to require firmware flashes to even get something that worked well, and oddly enough Nvidia used to be better luck than AMD. The couple of people who are actually using this setup and not scrapping are probably developers and have a much deeper understanding of what's going on with their system and can debug at a lower level. I don't think GPU passthrough is a priority for VMware, so I'd guess KVM might be the most likely route we might see an easier path with. Right now, I would say without a doubt that the UnRaid guys have the best solution. I was able to go through their web interface and setup GPU passthrough quite easily and actually get it to work. But I don't recall if that system stayed working either after a few reboots. That and for an all in one solution I was concerned with the security / flexibility of the hypervisor.

There are three solutions that I know work and I've thought about how to set them up. One is HyperV. Rather than doing the whole GPU passthrough, you can use GPU acceleration in an RDP session. That actually works and is stable, but required extra licensing to use. The tradeoff is that it's definitely not bare metal performance, so DX11 / 12 of modern titles isn't going to happen. Another possibility is Virtualbox. You can pass GPU performance to the VM, and that works fairly well. It might be possible to figure out a way to access the console of your VM in a way that would allow you to just run multiple VMs side by side. The last one I haven't tried, but it should work is using ESX, but with VMware View. Once again hardware accelerated clients that you access through a protocol remotely, and give you 3d accelerated graphics on the other side.

Personally I'm more hopefully the open source guys will try to chase the GPGPU crowd and come up with a free solution to Microsoft and Vmware's solutions so we can just divide GPU time between VMs. Performance wouldn't be quite as high as native, but it would probably work well enough and be less complicated than try to give a physical piece of hardware to a virtual machine.
 
So I am looking at doing a project like this, but haven't purchased the hardware for it yet. Am I correct in understanding that I can avoid all the woes in this thread if I just buy an AMD GPU?
 
Not really, i am using an AMD gpu (380)and under ESXi 6.5 January update GPU pass through fails and hangs ESXi requiring a force reboot.

You want to use something like the R7 450, 460, etc. The older AMD cards do not work well with ESXi unless you go very old.

would be curious what the change is that made such a difference, since the 4 series was a re-branded 3 series essentially. There are also many threads on other devices hanging on pass-through, such as NIC's from broadcom / Dell.

The 4 series brings some PCI bus resetting features that ESXi needs to properly power down/up the card with the VM. I had a lot of trouble with the 2 and 3 series cards, but the RX 460 works perfectly fine passed through to Windows and Linux VMs.
 
mmmm, so their may still be hope for me to virtualize my desktop then, that is the only thing stopping me right now was that, the video card.
 
Try KVM instead of ESXi. I have a GTX 1070 passed through to a Win10 VM for gaming.

Presume it does USB pass through as well then?

Xenserver can do GPU but has no USB
Hyper-V does the RemoteFX for video..
ESXi is picky...

:D

Yes, I passthrough a USB port for USB to ethernet converter for my xbox controller.
For keyboard / mouse I use Synergy.
