Xen Paravirt Operations Domain 0 Serial Console Problem

Xen Paravirt Operations Domain 0 Serial Console Problem

[Mr. Teo En Ming (Zhang Enming)]

Hi All,

I have tried to configure serial console for Xen hypervisor, dom 0 
kernel and Linux login but it does not seem to be working.

Here is my grub configuration for serial console:

title Fedora (2.6.31-rc6-enming.teo) Serial Console
         root (hd0,0)
         kernel /xen.gz iommu=1 com1=115200,8n1 console=com1
         module /vmlinuz-2.6.31-rc6-enming.teo ro 
root=/dev/mapper/vg_fedora11_host-lv_root selinux=0 console=ttyS0,115200
         module /initrd-2.6.31-rc6-enming.teo.img

Is the above configuration correct? On my Intel Desktop Board DQ45CB, I 
have a COM1 header on the PCB and I have connected an external serial 
port to this header and also enabled COM1 in the BIOS.

After selecting the above entry in GRUB still on VGA, a cursor at the 
top left corner of the monitor shows up, which means Xen and Dom 0 
kernel are booting up on the serial console and not on VGA.

However, after some time, a login prompt finally displays on my VGA 
monitor! Isn't it NOT supposed to show up on VGA and should show up in 
serial console instead?

All the while I get nothing displayed on the Windows laptop connected to 
the serial console of the Xen machine. I am using Windows Hyper Terminal 
with a null modem cable and a USB-to-Serial converter cable.

After seeing nothing on Hyper Terminal, I go to the VGA console (tty1) 
and keyboard and pressed CTRL-ALT-DEL to reboot the Xen machine.

Then finally I see this screenshot:

http://2.bp.blogspot.com/_zzjv8MCM2sk/SpK6D_eSIfI/AAAAAAAAATs/NdSPpfddTvQ/s1600-h/xen+serial+console.JPG

After that, I select rebooting using serial console but I still see 
nothing on Hyper Terminal.

May I know what's happening and what's wrong with serial console?

Thank you.

Hi,

The main purpose of doing this is that I want to boot using serial 
console and free up the VGA card for direct access by the Windows HVM 
guest using VT-d IOMMU. But it seems I cannot get serial console working.

Please advise.

Thank you.

paste from that page:


Working example grub.conf with serial console output:

You also need to have the gettys configured properly.

Dear Pasi,

Thanks for your help! It works!

I wonder why this didn't work:

title Fedora (2.6.31-rc6-enming.teo) Serial Console
         root (hd0,0)
         kernel /xen.gz iommu=1 com1=115200,8n1 console=com1
         module /vmlinuz-2.6.31-rc6-enming.teo ro
root=/dev/mapper/vg_fedora11_host-lv_root selinux=0 console=ttyS0,115200
         module /initrd-2.6.31-rc6-enming.teo.img

And this worked:

title pv_ops dom0-test (2.6.29-rc7-tip) with serial console
         root (hd0,0)
         kernel /xen-3.3.gz dom0_mem=1024M loglvl=all guest_loglvl=all com1=19200,8n1 console=com1
         module /vmlinuz-2.6.29-rc7-tip ro root=/dev/vg00/lv01 console=hvc0 earlyprintk=xen
         module /initrd-2.6.29-rc7-tip.img

Anyway, I still got a tty1 output! I thought that after using serial console, it is not supposed to output to a monitor anymore?

As a result of this, I still can't hide the VGA card from dom 0 and pass it through to the Windows Dom U.

Any ideas?

Well you still haven't disabled the VGA display adapter..
And most probably you still have gettys configured aswell.

Oh, I guess pv_ops dom0 still doesn't have pciback. 
I wonder how to do it then..

Dear Pasi,

How do I disable the VGA display adapter? Stop the vga card kernel 
module from loading? Add it to /etc/modprobe.d/blacklist.conf? Under 
pv-ops dom 0, there is no nouveau kernel module. And nvidia kernel 
module cannot work in pv-ops dom 0 too.

How do I disable all the various tty from 1 to 7?

I still need to leave ttyS0 enabled, as I need the serial console.

As for hiding vga card from dom 0, I cannot use pciback as I am using 
pv-ops dom 0. I need to use pci-stub.

Re: Xen Paravirt Operations Domain 0 Serial Console Problem

[Mr. Teo En Ming (Zhang Enming)]

Ah I know where to disable all the tty already

It's no longer in /etc/inittab. Fedora 11 is using upstart.

tty1 to tty6 are in /etc/event.d

/etc/event.d/tty1
/etc/event.d/tty2
/etc/event.d/tty3
/etc/event.d/tty4
/etc/event.d/tty5
/etc/event.d/tty6

If I disable all the above tty, will I be able to hide vga card from dom 
0 since it is no longer displaying to the monitor?

Or do I still need to disable the vga card? How do I do that?

Thank you.

Dear Pasi,

I wonder how this guy Ng Beng Heng at the University of Michigan did it.

No

The video card is enabled by the BIOS and the kernel and also Xen then
always use it.

So I guess you need to have additional/extra video card that you'll
passthrough.

I have both the onboard Intel GMA 4500 and the PCI Express x16 NVIDIA Geforce 8400 GS.

Ng Beng Heng at the University of Michigan has done it. He's using the same Intel DQ45CB as me.

Re: Xen Paravirt Operations Domain 0 Serial Console Problem

[Mr. Teo En Ming (Zhang Enming)]

[-- Attachment #1.1: Type: text/plain, Size: 1787 bytes --]

I find that following the instructions here at Xen Wiki VtdHowTo don't work:


    Binding Devices to pci-stub

If using pv-ops dom0, also can use pci-stub to hide devices for 
assignment (example PCI device 01:00.0) * lspci -n * locate the entry 
for device 01:00.0 and note down the vendor & device ID 8086:10b9 .

...
01:00.0 0200: 8086:10b9 (rev 06)
...

* then use following commands to hide it: .

echo "8086 10b9">  /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:01:00.0">  /sys/bus/pci/devices/0000:01:00.0/driver/unbind
echo "0000:01:00.0">  /sys/bus/pci/drivers/pci-stub/bind

When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says permission denied.

My NVIDIA graphics card is using BDF 01:00.0. When I change directory to
/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at all.

Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config, it complains about pciback but I am using paravirt-ops dom 0 kernel.

And when I tried the "xm pci-list-assignable-devices", nothing shows up.

I have already specified iommu=1 in grub.

Hope the Intel folks can assist in this matter.

Hi

When I boot up the computer using onboard Intel GMA 4500 as the primary 
VGA controller, I could still see the NVIDIA Geforce 8400 GS PCI Express 
x16 card in lspci.

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset 
Integrated Graphics Controller (rev 03)
01:00.0 VGA compatible controller: nVidia Corporation GeForce 8400 GS

Dear Beng Heng,

I understand that you got VGA passthrough working with Intel DQ45CB and 
an PCI-E x16 ATI Graphics card.

I have Intel DQ45CB and NVIDIA Geforce 8400 GS PCI-E x16.

Could you share with me in details how you got VGA passthrough to work 
with ATI PCI-E x16 when you set onboard VGA as your primary video adapter?

Thank you.

RE: Xen Paravirt Operations Domain 0 Serial Console Problem

[Han, Weidong]

[-- Attachment #1.1: Type: text/plain, Size: 2682 bytes --]

What version of Xen are you using? Make sure after c/s 19893, which enables pci-stub to hide devices for assignment.

It works fine for me.

 > When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says permission denied
It doesn't matter. It is the same to pciback. You will get the same message when you do "cat /sys/bus/pci/drivers/pciback/new_id".

After use commands to hide 01:00.0 with pci-stub, can you see it use command 'ls /sys/bus/pci/drivers/pci-stub/'?


Regards,
Weidong

I find that following the instructions here at Xen Wiki VtdHowTo don't work:

Binding Devices to pci-stub

If using pv-ops dom0, also can use pci-stub to hide devices for assignment (example PCI device 01:00.0) * lspci -n * locate the entry for device 01:00.0 and note down the vendor & device ID 8086:10b9 .

...

echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind

When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says permission denied.

My NVIDIA graphics card is using BDF 01:00.0. When I change directory to
/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at all.

Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config, it complains about pciback but I am using paravirt-ops dom 0 kernel.

And when I tried the "xm pci-list-assignable-devices", nothing shows up.

I have already specified iommu=1 in grub.

Hope the Intel folks can assist in this matter.

RE: VGA Passthrough with Intel DQ45CB and NVIDIA Geforce 8400 GS PCI Express x16

[Han, Weidong]

[-- Attachment #1.1: Type: text/plain, Size: 5488 bytes --]

Per our investigation, you cannot copy VGA bios from host 0xc0000 to guest for secondary gfx assignment. You can load it from a file.

In addition, if you want to passthrough Nvidia G8400, you need to 1:1 map its MMIO BARs.

Weidong

all.



Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config,
it complains about pciback but I am using paravirt-ops dom 0 kernel.



And when I tried the "xm pci-list-assignable-devices", nothing shows up.



I have already specified iommu=1 in grub.



Hope the Intel folks can assist in this matter.

What version of Xen are you using? Make sure after c/s 19893, which enables
pci-stub to hide devices for assignment.
 
It works fine for me.
 
 > When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says

It doesn't matter. It is the same to pciback. You will get the same message
when you do "cat /sys/bus/pci/drivers/pciback/new_id".
 
After use commands to hide 01:00.0 with pci-stub, can you see it use command
'ls /sys/bus/pci/drivers/pci-stub/'?

Xen 3.4.1 doesn't include the changeset 19893, so it cannot work for you. Basically, I use 2.6.18 dom0 with Xen 3.4, and use pv-ops dom 0 with xen-unstable. Anyway, you can port the c/s 19893 to your code, and try again.

Dear Weidong,
 
I am using Xen 3.4.1 testing with pv-ops dom 0 kernels 2.6.30-rc3 or
2.6.31-rc6.
 
May I know where I can download changeset 19893 source code and patch Xen 3.
4.1 testing with this changeset?
 
Thank you.

Xen 3.4.1 doesn't include the changeset 19893, so it cannot work for you.
Basically, I use 2.6.18 dom0 with Xen 3.4, and use pv-ops dom 0 with
xen-unstable. Anyway, you can port the c/s 19893 to your code, and try
again.

What version of Xen are you using? Make sure after c/s 19893, which enables
pci-stub to hide devices for assignment.
 
It works fine for me.
 
 > When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says

It doesn't matter. It is the same to pciback. You will get the same message
when you do "cat /sys/bus/pci/drivers/pciback/new_id".
 
After use commands to hide 01:00.0 with pci-stub, can you see it use command
'ls /sys/bus/pci/drivers/pci-stub/'?

I find that following the instructions here at Xen Wiki VtdHowTo don't work:



Binding Devices to pci-stub

If using pv-ops dom0, also can use pci-stub to hide devices for assignment
(example PCI device 01:00.0) * lspci -n * locate the entry for device 01:00.
0 and note down the vendor & device ID 8086:10b9 . 

...

01:00.0 0200: 8086:10b9 (rev 06)

...


* then use following commands to hide it: . 

echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id

echo "0000:01:00.0" > /sys/bus/pci/devices/0000:01:00.0/driver/unbind

echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind



When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says
permission denied.



My NVIDIA graphics card is using BDF 01:00.0. When I change directory to 

/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at
all.



Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config,
it complains about pciback but I am using paravirt-ops dom 0 kernel.



And when I tried the "xm pci-list-assignable-devices", nothing shows up.



I have already specified iommu=1 in grub.



Hope the Intel folks can assist in this matter.

Per our investigation, you cannot copy VGA bios from host 0xc0000 to guest
for secondary gfx assignment. You can load it from a file.
 
In addition, if you want to passthrough Nvidia G8400, you need to 1:1 map
its MMIO BARs.

Could you share with me in details how you got VGA passthrough to work with

Dear Weidong,

I am using Xen 3.4.1 testing with pv-ops dom 0 kernels 2.6.30-rc3 or 2.6.31-rc6.

May I know where I can download changeset 19893 source code and patch Xen 3.4.1 testing with this changeset?

Thank you.

Xen 3.4.1 doesn't include the changeset 19893, so it cannot work for you. Basically, I use 2.6.18 dom0 with Xen 3.4, and use pv-ops dom 0 with xen-unstable. Anyway, you can port the c/s 19893 to your code, and try again.

What version of Xen are you using? Make sure after c/s 19893, which enables pci-stub to hide devices for assignment.

It works fine for me.

 > When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says permission denied
It doesn't matter. It is the same to pciback. You will get the same message when you do "cat /sys/bus/pci/drivers/pciback/new_id".

After use commands to hide 01:00.0 with pci-stub, can you see it use command 'ls /sys/bus/pci/drivers/pci-stub/'?


Regards,
Weidong

I find that following the instructions here at Xen Wiki VtdHowTo don't work:

Binding Devices to pci-stub

If using pv-ops dom0, also can use pci-stub to hide devices for assignment (example PCI device 01:00.0) * lspci -n * locate the entry for device 01:00.0 and note down the vendor & device ID 8086:10b9 .

...
01:00.0 0200: 8086:10b9 (rev 06)
...


* then use following commands to hide it: .

echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:01:00.0" > /sys/bus/pci/devices/0000:01:00.0/driver/unbind
echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind

When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says permission denied.

My NVIDIA graphics card is using BDF 01:00.0. When I change directory to
/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at all.

Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config, it complains about pciback but I am using paravirt-ops dom 0 kernel.

And when I tried the "xm pci-list-assignable-devices", nothing shows up.

I have already specified iommu=1 in grub.

Hope the Intel folks can assist in this matter.

xend: allow pv_ops kernel driver pci-stub to hide devices for assignment

pciback is used by VT-d to hide device for assigment. But in pv-ops
dom0, pciback is not supported yet. Fortunately, pci-stub module is
used to hide device in Linux for KVM VT-d device assignment and it's
included in pv-ops dom0. So can use pci-stub to hide devices for
assignment.

Device must be hidden before assignment. Control panel has checks if
devices can be assigned or not, and can list assignable devices via
reading devices owned by pciback. This patch changes the checks, and
also list assignable devices which are owned by pci-stub. Use pci-stub
to hide devices, and use this patch to pass checkes in control panel,
device assignemnt with VT-d works on Xen with pv-ops dom0.

Hi Weidong, 
 
I have taken a look at the patch code you have attached. The date is 6 July
2009, which is one month older than the Xen 3.4.1 testing code that I am
currently using.
 
Is this pci-stub patch already in Xen 3.4.1 testing changeset of 6 August
2009? If it is not merged into Xen 3.4.1 6 Aug 2009 changeset, then I would
have to patch my current Xen code using this patch file.

Xen 3.4.1 doesn't include the changeset 19893, so it cannot work for you.
Basically, I use 2.6.18 dom0 with Xen 3.4, and use pv-ops dom 0 with
xen-unstable. Anyway, you can port the c/s 19893 to your code, and try

Hi Weidong,
 
I believe I am using Xen 3.4.1 with changeset of 6 August 2009. I can't
remember the changeset number. I will check and get back to you later.

What version of Xen are you using? Make sure after c/s 19893, which enables
pci-stub to hide devices for assignment.
 
It works fine for me.
 
 > When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says

It doesn't matter. It is the same to pciback. You will get the same message
when you do "cat /sys/bus/pci/drivers/pciback/new_id".
 
After use commands to hide 01:00.0 with pci-stub, can you see it use command
'ls /sys/bus/pci/drivers/pci-stub/'?
 
 
Regards,
Weidong

Problem


I find that following the instructions here at Xen Wiki VtdHowTo don't work:



Binding Devices to pci-stub

If using pv-ops dom0, also can use pci-stub to hide devices for assignment
(example PCI device 01:00.0) * lspci -n * locate the entry for device 01:00.
0 and note down the vendor & device ID 8086:10b9 . 

...

01:00.0 0200: 8086:10b9 (rev 06)

...


* then use following commands to hide it: . 

echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id

echo "0000:01:00.0" > /sys/bus/pci/devices/0000:01:00.0/driver/unbind

echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind



When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says
permission denied.



My NVIDIA graphics card is using BDF 01:00.0. When I change directory to 

/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at
all.



Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config,
it complains about pciback but I am using paravirt-ops dom 0 kernel.



And when I tried the "xm pci-list-assignable-devices", nothing shows up.



I have already specified iommu=1 in grub.



Hope the Intel folks can assist in this matter.

[-- Attachment #1.1: Type: text/plain, Size: 9150 bytes --]

Hi Weidong,
 
I understood now. http://xenbits.xensource.com/xen-3.4-testing.hg and
http://xenbits.xensource.com/xen-unstable.hg are completely different
mercurial branches. I am using xen 3.4.1 testing which means my code won't
have the pci-stub patch you have attached.
 
When I go back home after work I will do:
 
# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-unstable.hg
# cd xen-unstable.hg
# make xen
# make install-xen
# make tools
# make install-tools
 
Is xen-unstable very unstable? Will it work with my pv-ops dom 0 kernels
2.6.30-rc3 and 2.6.31-rc6? I believe I only have to download, compile and
install xen-unstable right? I shouldn't have to do anything with my current
pv-ops dom 0 kernels?
 
Thank you.

Hi Weidong, 
 
I have taken a look at the patch code you have attached. The date is 6 July
2009, which is one month older than the Xen 3.4.1 testing code that I am
currently using.
 
Is this pci-stub patch already in Xen 3.4.1 testing changeset of 6 August
2009? If it is not merged into Xen 3.4.1 6 Aug 2009 changeset, then I would
have to patch my current Xen code using this patch file.

Xen 3.4.1 doesn't include the changeset 19893, so it cannot work for you.
Basically, I use 2.6.18 dom0 with Xen 3.4, and use pv-ops dom 0 with
xen-unstable. Anyway, you can port the c/s 19893 to your code, and try
again.

It shouldn't be _very_ unstable, but you might see some problems every now
