[Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem
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.

Re: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem
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.

Re: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem
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?

Re: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem
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. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics Engineering) BEng(Hons)(Mechanical Engineering) Technical Support Engineer Information Technology Department Asiasoft Online Pte Ltd Tampines Central 1 #04-01 Tampines Plaza Singapore 529541 Republic of Singapore Mobile: +65-9648-9798 MSN: teoenming@hotmail.com Alma Maters: Singapore Polytechnic, National University of Singapore On 08/25/2009 01:57 AM, Pasi Kärkkäinen wrote:> On Tue, Aug 25, 2009 at 01:34:54AM +0800, Mr. Teo En Ming (Zhang Enming) wrote: > >> Dear Pasi, >> >> Thanks for your help!

Re: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem
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?

Re: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console 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.

RE: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem
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/'?

[Xen-devel] RE: VGA Passthrough with Intel DQ45CB and NVIDIA Geforce 8400 GS PCI Express x16
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.

RE: [Xen-devel] Xen Paravirt Operations Domain 0 SerialConsoleProblem
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.

RE: [Xen-devel] Xen Paravirt Operations Domain 0 SerialConsoleProblem
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.
