Access to the gui keeps dropping out.  Losing the love for VM's.....

 

Might be going back to the TVHeadend plugin and 14b soon.  I'll never get these last 2 lost days back 

Thanks for all of your help CHBMB anyway.  Got to get the TV working before the Wife explodes! 

Access to the gui keeps dropping out.  Losing the love for VM's.....

 

Might be going back to the TVHeadend plugin and 14b soon.  I'll never get these last 2 lost days back 

 

I know that feeling.  Sorry I can't be more help, but I'm at work and been posting from my phone and using my VPN to access my own setup to look at things.

No probs mate. ATB

I can't be beaten by it......

When I try and run the VM i get a green error message at the bottom of the screen.  It runs fine without the PCI passthrough changes.

 

Can somebody cleverer than me please take a look at my xml file and see if it needs changing?

 

Should I be doing something with the go or sys cfg files?

 

Thanks

this is my syslinux file:

 

default /syslinux/menu.c32

menu title Lime Technology

label unRAID OS

  menu default

  kernel /bzimage

  append pcie_acs_override=downstream initrd=/bzroot

  append /xen --- /bzimage --- /bzroot

label Xen/unRAID OS Safe Mode (no plugins)

  kernel /syslinux/mboot.c32

  append /xen --- /bzimage --- /bzroot unraidsafemode

 

I added the "pcie_acs_override=downstream" as instructed by older forum posts.  Not sure if that was the right thing to do.

 

This is my go file:

 

#!/bin/bash

# Start the Management Utility

/usr/local/sbin/emhttp &

/usr/local/sbin/vfio-bind 0000:03:00.0 0000:04:00.0

 

I added the "/usr/local/sbin/vfio-bind 0000:03:00.0 0000:04:00.0" as per previous posts. Not sure that I should do this either.

 

Whatever I do I cannot pass the PCI devices through.  I dont know what else to try.

 

Any ideas please?

I believe that your first line in your xml needs to look something like this for passthrough of devices

 

<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>

 

This may be updated to something different, not sure, I haven't played in passing thru anything recently, but it was required prior.

Also trust me, I know all too well about wasting 2 days on it....LOL..

Thanks a lot.  This is driving me crazy!! I'll take a look now

vfio-bind 0000:03:00.0 0000:04:00.0

 

I added the "/usr/local/sbin/vfio-bind 0000:03:00.0 0000:04:00.0" as per previous posts. Not sure that I should do this either.

Also, per JonP in another thread, no longer use vfiobind, it isn't needed and likely causing issues.

 

*edit (thinking about it more)  - I suppose since this isn't well documented, maybe (?) you still need it to bind to vfio since what you are passing through isn't being configured through the VM tab (which would then work its magic, and not require the address to be bound).

Since that's the case and you are editing this yourself, maybe you do need it, I honestly can't say.

I try to add <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>

 

when the vm is offline, but it keeps reverting back to original state.

If you change the top line, however never specify the pass through under the

<qemu:commandline>

STUFFFFFFFFFFFFFF

</qemu:commandline>

 

it will change it back, because you are not passing anything.

Change that top line, then add your device in the bottom line here.

<qemu:commandline>

      <qemu:arg value='-device'/>

      <qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1'/>

      <qemu:arg value='-device'/>

      <qemu:arg value='vfio-pci,host=0#:00.1,bus=pcie.0'/>/>

  </qemu:commandline>

 

This is an example, enter your device location, etc...as needed.

I have NO idea if you HAVE to have this part first prior to the device if not passing a GPU, I asked once and never got an answer.

 

<qemu:arg value='-device'/>

<qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1'/>

 

Hopefully I am not making this worse on you..

 

sorry that last one went straight over my head 

 

where is the <qemu:commandline>?

You couldnt make it worse.  I keep giving up and going back to 14b.

 

Only to come back and try again

Things may have changed... 

 

Did you read through this thread?

http://lime-technology.com/forum/index.php?topic=38259.0

sorry that last one went straight over my head 

 

where is the <qemu:commandline>?

 

Explained in this post at the bottom.

http://lime-technology.com/forum/index.php?topic=35732.0

Yeah I did read that thread.  I was just about to reply about not needing the qemu if using the"Simple" (LOL) method.

 

I would like to just chane the top line of my XML to see if that works.  Not sure how to do it outside of the VM gui

Actually think this thread holds the answers for me:

 

https://lime-technology.com/forum/index.php?topic=38569.0

Could somebody please tell me how to edit my xml file outside of the VM gui?

 

When I change it in the gui it reverts back

My VM is in raw format and is stored on a SSD.

 

I think that the info for VM's is scattered all over the place and of all ages and relevance.  I don't really know if I should be changing the first line of my XML file if I'm not using qemu.  Should I be changing the XML field due to the raw format or SSD? Should I be changing my GO file?  Should I be changing my Syslinux file?

 

I have been from A to Z and back again for days.  I will be licking the windows soon.

 

Any pearls of wisdom?

 

Looks like I'm off back to 14b. Again......

Actually think this thread holds the answers for me:

 

https://lime-technology.com/forum/index.php?topic=38569.0

 

This thread I don't think is relevant..

 

I've been busy the last couple of days.  Got a few things to do today but I'll try and have a look and compare your XML with mine and see if anything springs to mind.  Will be easier as I'm on a proper PC rather than my Nexus 5!

Right I'm going to post my config as I know this works, just tested it on 6b15

 

Before you start, check the settings for PCIe ACS Override are as below.

EDIT: Apparently there may be some issues with PCIe ACS Override so ensure this is set to off, I haven't yet had chance to investigate with my own machine but the info comes from a very knowledgeable forum user.  I have also removed references to this in syslinux.cfg - the updated config is posted below.

 

EDIT2: Now had a chance to check this and the below config is working as far as I can tell.  There is no need to edit your syslinux.cfg and PCIe ACS Override should be set to off.  I have modified the text and pictures below so it is all current and correct as far as I understand things.

I can confirm this method works with beta14b and beta15

 

My syslinux.cfg - note this may been different for AMD CPUs

Now to add in my card I paste in my passthrough config..

 

Generically, the address is

aa:bb:c

So I need to paste into

 

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0xaa' slot='0xbb' function='0xc'/>
      </source>
    </hostdev>

 

My Card's address is

02:00.0

Which becomes

 

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
      </source>
    </hostdev>

 

This goes above these last two lines in your xml, ie in the devices section.

  </devices>
</domain>

 

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

<alias name='hostdev0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>

 

So the relevant part becomes:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
      </source>
      <alias name='hostdev0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
    </hostdev>

 

Install the OS and boot up once it's completed, my device manager shows this:

 

Install my drivers:

 

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)

I know that's for Windows, but I'm more familiar with Windows, and I know what to expect to happen so it was easier for me to set it up from scratch on the new beta.  I will have a go with Ubuntu server but the only thing I think would be different is I'd leave Hyper-V off as that is Windows specific (Just checked - it's not even an option when operating system is set to Other.

Change

 

 <graphics type='vnc' port='5900' autoport='yes' websocket='5700' listen='0.0.0.0'>

 

And add in

 keymap='en-gb'

 

To become

<graphics type='vnc' port='-1' autoport='yes' websocket='5700' listen='0.0.0.0' keymap='en-gb'>

 

Otherwise it's as confusing as hell when you come to type stuff in!! 

Oh monkeyair, just thought of another pitfall, make sure your tvheadend docker isn't autostarting, I've found that if Unraid tries to use the device I want to passthrough, either via a plugin or docker then it won't work in a VM until after a reboot.  That may be your problem.
