Unraid Monthly Newsletter. Unraid OS 6.New vfio-bind method. This file should contain a single line that defines the devices:. The function of the script is to bind each specified device to the vfio-pci driver, which makes them available for assignment to a virtual machine, and also prevents the Linux kernel from automatically binding them to any present host driver.

In addition, and importantly, this script will bind not only the specified device sbut all other devices in the same IOMMU group as well. Specifying a single device either one on the BIND line is sufficient to bind both device to vfio-pci.

The implication is that either all devices of an IOMMU group are bound to vfio-pci or none of them are. Right now most of us I guess have something like this in the Syslinux configuration since is the dicussed method in forum and some youtube videos.

So considering the new method and my current configuration to passthourgh a pci network card, what should I add, remove, keep of my current settings.

You don't have to do anything if using vfio-pci. This is for those that use xen-pciback. So if someone was going to be setting up some devices for PT in a vanilla system, nothing PT'd yet. Should we use this new method, or the example above where it's appended in the syslinux config? To expand on saarg explanation: the "vfio-pci.

This parameter identifies devices using "Vendor:Model" strings where Vendor and Model are numeric values assigned by the device manufacturer. This is easy because that string will never change.

The disadvantage is if you have two or more of the exact same device in your server, then all of them will be "invisible" to Linux. The other kernel parameter available was "xen-pciback. Each of those values are also numbers that identify the device according to where it exists in your server PCI bus topology. The advantage with this method is that an exact device can be identified independent of whether another of the same device exists in the server.

The problem we ran across was that xen-pciback.

UnRAID 6/VM Guest Support

Note that in general, kernel evolution is moving away from kernel parameters and to more flexible methods. For example, "isolcpus" is really deprecated and there is alternate method of isolation CPU's using config files which we will adopt in a future Unraid OS release. As you can see, there is currently no "perfect" way of maintaining permanent assignment of devices to VM's. So, in my planning, I am going to be passing 2 x identical USB 3.

Since I will have 2 x identical sets of matching hardware, I assume I should use this new method? Either method should work, note all it does is tell the kernel not to bind any driver to the device sthough actually it does bind vfio stub driver this is what prevents other drivers from binding. Using ACS override is "ok" in most Unraid applications because usually you are in complete control over what VM's are running and what is running in each VM.

The cloud-server guys can't use ACS override because doing so theoretically allows one VM to gain access to another VM running on same hardware - this is why the ACS override patch will never be accepted into the official kernel source tree. Do these changes have anything to do with my new issue, or is it just coincidence and I need to look elsewhere for a solution to this new problem? That issue have nothing to do with the new method.

Probably best to open a new thread about the issue. Now it works like a charme.Official Documentation Contents List. Unraid 6 currently supports the virtualization of nearly any bit operating system.

Not all OSes have been tested, but those that have are listed on this page. From time to time, the Fedora project will release new versions of the VirtIO drivers which may resolve bugs and improve performance. In some cases, driver updates may be required for upgrading your Windows OS from one version to another e.

To update your drivers, perform the following steps:. Hibernation was originally designed as a feature for laptops to allow users to maintain a system's state without consuming power. This basically involved dumping the RAM of the system to local storage and then powering down the system. Then when the system powers back on, instead of going through a normal Windows boot process, the system would simply restore the saved state from hibernation.

With VMs, hibernation is a useful way to save the state of a VM when you need to either power down or reboot the host.

In order to make correct use of hibernation, you must first do two things. There is no confirmation when complete, but a command box may appear briefly while its installing.

After the installation of a Windows VM, there are several things you can do to optimize your VM's performance and flexibility. None of these are required, but should you run into performance issues with your Windows VMs, following these guides may improve things for you. Fast Startup is a feature introduced with Windows 8 that can improve boot times on physical PCs.

Unleash Your Hardware

However, as a VM, this can cause problems when initializing hardware after shut down this can especially be true if you are assigning physical devices to virtual machines. It is for these reasons we highly encourage users to set their power management settings to High performance mode.

Even with fast startup disabled, technically the system is still able to "hibernate" as a user-controllable function. The trade-off, however, is that a hidden file called Hiberfil.

By disabling hibernation as a feature entirely, you can reclaim many GB of space on your virtual disk and reduce overhead relating to disk IO inside the VM. To improve overall VM performance, it is recommended to disable this service from running in Windows. If Windows disk defragmenter is set to automatically run on a schedule, you should disable it.

This is not necessary for VMs and can cause unnecessary wear and tear on your physical storage devices. Because Windows is a virtual machine, there is little to no benefit in leveraging it's power management features.

In fact, these features can make using VMs more difficult, as it requires another device to then access the webGui to resume a VM that was suspended due to a period of inactivity.

You will also need to be using Windows Professional edition the Home edition does not include this feature. If you are assigning a graphics device to your Windows guest that uses an HDMI connection and you wish to push audio through that connection, you may need to perform a registry modification in Windows to ensure the audio driver remains working properly this is most prevalent with NVIDIA devices.

Here's the procedure for doing this:.

If you cannot find a line that mentions MSI as a capability, it means your device does not support this. If you have a Windows 7 or 8.For "bus", "slot", and "function", this should be your PCI device address.

In theory, you shouldn't have to use vfio-bind either with this. Instead, libvirt should manage all that for you binding to the vfio-pci driver. This is the supported method. Is there a particular reason that there are two different machine types available? I can see this creating a lot of confusion if certain XML elements apply to one but not the other. Q35 is a more modern machine type, but still heavy in development and not fully supported by libvirt yet.

That said, it's advised that new users as of the latest beta first try the PC type before attempting Q The fate of the Q35 machine type longer term is yet to be determined.

With windows vms that are already installed though, this will cause you to need to reactivate your Windows license as this will look like you're changing the entire motherboard.

For VMs that utilize pci pass through, GPUs or otherwise, you'll need to adjust your qemu command line section of the xml to not use pcie. Share your xml and I'll reply with the edits to make. Thanks for clearing that up. Here's my xml, I'll be interested to know what changes are required. There are two things to change. The first is the machine type setting and the second is in the qemu command line arguments. I've highlighted the parts that should be changed below:.

However, if you are going to use the machine type of PC, I would actually first try to eliminate the QEMU arguments altogether and use the method I posted at the beginning of this thread.

Give it a shot!! Just put a in front of that line in your go file and save. This way if it doesn't work, you just remove the and its back to as it was. You should be able to remove it. Works like a treat, my go file is now very much neater.

Cheers jon for walking me through this, made it much easier than the trial and error rigmarole I would have had to go through by myself, much appreciated once again. So, I've been helping a fellow forumite and wrote up this guide in another thread. Thought it might be useful here for those new to KVM as there is a lot of confusion surrounding passthrough. I have also removed references to this in syslinux. There is no need to edit your syslinux. I have modified the text and pictures below so it is all current and correct as far as I understand things.

Once you've pasted it in and saved it then you may notice two extra lines are added automatically. This is the KVM assigning your passthrough card a slot on the virtual machine, so don't worry about that.

In my case that was. For completeness here's my finished xml, note that KVM manager does reorder things a little bit, the important thing to avoid errors is to paste it into the correct place to start with above the last two lines. And the resulting XML file, but when I try to launch the VM, nothing happens no entries in log file, no errors displayed on screen.

Note: Your post will require moderator approval before it will be visible. Restore formatting.An unRAID server is made up of a standard set of parts. This page discusses some of the general issues that need to be considered when designing your server, and how they influence the parts that you choose.

The Hardware Compatibility page should be read in conjunction with this page. It lists brands and models that have been reported by users to work with unRAID builds, and includes recommended builds, with links to online stores in several countries.

Security of data is paramount with any filestorage system, including unRAID. Although unRAID provides for a parity disk to protect against data loss or other malfunction, it is best to reduce risk further by using reputable brands, and products that have been tested by other users. The place where the server will be stored influences purchase and design decisions, both aesthetically and practically. Full tower and mid tower cases have plentiful space for hard drives, but are bulky and have a large footprint; if the server is to be in plain view, a smaller form factor or a more expensive and better looking case may be more acceptable.

For a standard unRAID server, focused on reading and writing files and calculating parity data, high-specification parts are not required. If the server will be used for CPU-intensive tasks, such as torrents, video encoding or virtual machines, higher specification CPUs with dual cores will be advantageous. If the server will be used for tasks such as running torrents or virtual machines, at least 4 GBs of RAM is recommended.

Using 1x2GB allows more room for future expansion up to 4 or 8 GB. Check that the memory matches the motherboard's DIMM slots. Just look for a motherboard with plenty of SATA ports. Also, a separate graphics card is not required by unRAID. Only purchase one if your motherboard does not have onboard video i.

They usually end in either a 60G or an 80G. There is a balance between the use of fewer, large capacity drives to reduce the amount of power required by the system, with an increased risk of large-scale data loss if two drives fail at the same time. Green or LP low power drives — or rpm — are often recommended both for parity and data because they are cooler, quieter, and use less power than higher speed drives.

Improved performance can be seen if both the parity drive and the data drives are of a faster rotational speed: having a rpm parity drive with all rpm data drives will not be of benefit. There is a compromise — having a rpm parity drive and one or more rpm data drives the drives that will be used most-used as well as some rpm data drives.If you are reading this message, Please click this link to reload this page.

If some how in the BIOS? Pros: Works great with unRaid which is based on Linux. Everyone that says it doesn't work with Linux has no clue what they are talking about or what they are doing.

I have had this installed and running since with no issues. Cons: After setting up a raid on my home server I was starting to see different errors on my hard drives. These are rpm seagate 3 TB seagate drives. I noticed that my raid would kick out a drive every so often which would cause the kernel to spawn a few "cpu locked" messages.

This was disconcerting. After further investigation the manufacturer of this card admits their drivers are not compatible with linux.

Centos 6. This was extremely disappointing and completely terrible as my raid was causing instability to the host itself. I then went to e-b-a-y and picked up an LSI 8i card. Same price and the shipping was fast. This card has been amazing and I have since reinstalled those earlier reported hard drives and they are running flawlessly. Contacts with the manufacturer have resulted in nothing. They state that these cards work in windows but are unsupported with my setup.

I'm frustrated as this is grounds for DOA. Overall Review: Buyer beware.

Cons: After reading the quick list of supported OS's I decided to buy two of these cards. I received them and installed them. My plan was to first run FreeBSD, no dice getting that working with these cards at all, So after that I went through 4 different Linux distributions, I only got it working after switching to a 3 year old centos distribution, this allowed me to install the 3 year old proprietary drivers, with their 3 year old bugs.

After some quick testing I noticed right away drives dropping out of the arrays, as well as more concerning cases of drives being readdressed blindly.By archedraftDecember 9, in VMs. One benefit is that USB will be plug n play on your virtual machines. Also, I have found that if you pass through USB devices separately the device name could change which will cause the VM to not start, but if you pass through the entire controller you will avoid this. Please be VERY careful when doing this. Now would be a great time to pull out the Motherboard Manual to take notes on see mine below.

Plug it into a spare USB slot and type. Repeat this step this for all your USB slots. Match the group with the device number. As you can see below, mine is part of group 5 and that is the only device on group 5.

If you have more than one device in the same group you will most likly have to pass them through to your VM as well, YMMV. As of unRAID 6. Now lets add that device number to the vfio-pci driver. Open your "go" file under config on your unRAID flash drive and add this line:.

This part of the code is needed no matter what and you shouldn't have to change anything see Hint 1 for more details :. Then add your USB code so when its all said and done it should look like this if you are only passing through an USB controller without a graphics card if you are passing through a graphics card as well see my config in step 11 for that example :.

In my above code my GPU is For me it's much easier to use the hostdev tag instead of the qemu:arg. It's just too much trouble with it when you don't know what you are doing. You then have to modify some parts of it to get it to work.

The good thing is that you do not have to care about which bus and address it's supposed to have in the VM. You only need to find out the host PCI address. The part you change is bus, slot and function. In your case it's 00 : You simply exchange the two numbers after the 0x. After you start the VM you will see that there are some lines added to the tag, but those you don't have to care about.

They get created automatically. If you copy a host device tag to pass through a new device, be sure to remove the two lines created after the. Doing so may allow you to coax certain USB ports to attach to one controller and others to the other controller s. It's honestly just a process of trial and error process of changing those settings, and then going through the above guide again to see if anything changed.

Well done arch. This is pretty much how I did it. You can play with xhci and ehci handoff settings in your bios as well to get multiple USB controllers accessible from onboard chip set.

Thanks, I know I will need to retrace my steps in the future so I better write it down somewhere.

UnRAID Add Ons

What better place than the forum and hopefully others find it useful. Excellent write up, thank you! I just setup my KVM and this couldn't come at a better time. I did a little bit of usb-investigation and not having much luck with pci passthrough.
