    ***GUIDE*** Passthrough Entire PCI USB Controller

    in VMs

    Posted · Edited by amstel

    Hey,

    started the routine but got confused O.o

     

    I am using:

    USB 2.0 on board(2 ports),

    USB 3.0 on board(4 ports),

    USB 3.0 Header (2 ports)

     

    my output: 

    ~#lspci | grep USB
00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31)

~#lsusb
Bus 002 Device 002: ID 0951:1666 Kingston Technology DataTraveler G4
Bus 002 Device 003: ID 0781:5590 SanDisk Corp.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 04b3:3025 IBM Corp. NetVista Full Width Keyboard
Bus 001 Device 004: ID 03f0:2b17 Hewlett-Packard LaserJet 1020
Bus 001 Device 003: ID 045e:0083 Microsoft Corp. Basic Optical Mouse
Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

IOMMU group 3
	[8086:a12f] 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31)

    well,

    looks like the 'USB 2.0 onboard' and the 'USB 3.0 Header',

    sharing the same bus (BUS 001).


    I only want to passthru all the devices from Bus 001,
    how do I do that?

    lags in wireless usb mouse - win10 vm

    hi, try the recommendations from the cpu pinning sticky thread...

    also try the tweaks plugin and reduce the cache values from the default ones (you could make them half if you have more than 16GB RAM on the host)

    -d

     

     

     

    Hey,

    thanks for the reply and sorry for the delayed response.

     

    I used the tweaks plugin and set the values as was suggested.

     

    but I'm still getting the same behavior with that wireless mouse.

     

    what else should I do?

     

    the battery is full,

    the usb dongle is 1meter from the mouse.

     

    lags in wireless usb mouse - win10 vm

    Hello,

     

    I'm using win10 VM that is passed thru nvidia GPU.

    I also passed the logitech wireless usb dongle to that machina.

    mouse is working mostly fine,

    but sometimes it is very laggy.

     

    when I move the mouse, the mouse pointer gets stuck in one place and after 1-2 seconds jumps straight to the next position.

     

    what should/could I do in order to fix this?

     

    Thanks.

     

    Performance Improvements in VMs by adjusting CPU pinning and assignment

    your core assignments look soooo wonky, which is fine because windows 10 doesn't care about where the cores come from (as shown through benchmarking tests) or even using threaded pairs.

     

    If you're using all the cores, there is no need to really specify an emulator pin. There might be a super small gain? But if you want to, make it 2 or 3

     

    mmm,

    well, I tested 4 different combinations with GeekBench cpu benchmark

    and those are the results (singlecore, multicore):

    4 cpu's, no isolation: 3805, 6951

    2 isolated cpus (1,3): 3323, 4041

    2 isolated cpus (1,3) + 2 shared cpus: 3632, 6588

    2 isolated cpus (1,3) + 2 shared cpus + emulatorpin=2: 3554, 6781

     

    it seems that the normal configurations gives the best benchmark result.

    what am I missing here?

     

    Thanks.

    Yes. Just because a cpu is isolated/not isolated from unRaid doesn't keep it from being assigned to a vm.

     

    If you do that, my suggestion would be to ensure that vcpu 0 of the vm is an isolated core, as windows and most other operating systems will use that as a primary resource and favor it, especially during initial booting of the vm. If you did not change it, then the vm and unraid would try to use that as primary, resealing in decreased performance. Also note that using the shared cores (non isolated) may contribute to latency, diminishing he point of isolating cores.

    well,

    I have changed cpu (1,3) to be isolated.

     

    now,

    I'd like to assign all 4 of them to the VM.

     

      <cputune>
        <vcpupin vcpu='0' cpuset='1'/>
        <vcpupin vcpu='1' cpuset='3'/>
        <vcpupin vcpu='2' cpuset='0'/>
        <vcpupin vcpu='3' cpuset='2'/>
        <emulatorpin cpuset='2'/>
      </cputune>

     

    do I still need to use the emulatorpin feature?

    if yes, which CPU should I assign there?

     

    Thanks.

    yes I know that,

    I just don't want the VM to be too slow, cause using 'only' 2 hyperthreaded cores (1 cpu).

     

    I will give those 2 different configurations a try and will test each to see which will act better.

     

    Thanks for the help!

    if you want to run your vm on those threads and want to increase performance and decrease latency, yes.

     

     

    you only need  1 cpu for emulator pin, use just cpu 2

     

     

    Yes and no. Yes if you are doing tasks which require more cpu power, like transcoding via plex docker or heavy downloading/etc... No if you're only running a vm and network file transfers since you need less cpu resources for unRaid.

     

    Thanks for the reply.

     

    I'm using the unraid (beside for the VM) for:

    TVHEADEND: record and stream DVB-T TV.

    Transmission: download/upload files 24/7.

    SMB: sharing local files for home TV streaming.

    quassel-core: connected to irc server.

     

    I guess that it should work well, is it?

     

     

    another question,

    can the unraid server use those isolated cpus while the VM is not running?

     

    Thanks.

    did that...

     

    now getting error message:

    An unknown PHP error occurred. This is most likely a syntax error in config.php in phpVirtualBox's folder. The most common errors are an unclosed quote or a missing semicolon in a configuration item that has been entered (e.g. location, username, or password).

     

    Depending on your PHP configuration, navigating directly to config.php in your web browser may display the PHP error message.

     

     

     

    I have changed the config.php file back to config.php-example

    and still getting the same error messages.

    I think you need to ask this in the apache webserver thread.

     

    Did you try to restart the server?

     

    I have uninstalled the plugin,

    then installed apache server as a docker, config looks bit different.

    after configuring few things, I am able to enter the phovirtualbox.

    but,

     

    am getting this message:

    An error occurred communicating with your vboxwebsrv. No more requests will be sent by phpVirtualBox until the error is corrected and this page is refreshed. The details of this connection error should be displayed in a subsequent dialog box.

     

    after clicking ok, receiving the following error:

    Could not connect to host (http://127.0.0.1:18083/)

     

     

     

    Thanks.

    Do you have a firewall that may be blocking this port?

     

    Also copy config.php-example to config.php and change this line:

     

    #var $noAuth = true;

    to 

    var $noAuth = true;

    remove # from beginning of line

     

    no firewall..

    did you notice that on the webserver plugin page it says:

    Status:Stopped

    ?

     

    what is wrong?

    Hey,

     

    I installed the virtualbox plugin,

    installed apache webserver, put the phpvirtualbox..

    now,

    when I connect to the webserver, I can see RECENT CONNECTIONS

    and

    ALL CONNECTIONS

     

    there is dolphin plugin there that works..

    but,

    how can I add new windows 7 for example?

     

    Thanks.
