XEN 4.1 error Critical Interrupt - Front panel NMI

[-- Attachment #1.1: Type: text/plain, Size: 1170 bytes --]

Hello Everyone,

I am quite new on XEN. I tried to installed XEN on my server and I know
this server series IBM Xeon 3,4 Ghz didn't have Intel VTx support so I am
pllaning to use paravirtualization.
I configure the server with Ubuntu Desktop  12.0464 bit as dom0 with XEN
4.1 64 hypervisor. The configuration using repositories exactly by this
tutorial https://help.ubuntu.com/community/XenProposed :

Installing Xen

Install a 64-bit hypervisor

sudo apt-get install xen-hypervisor-amd64

Modify GRUB to default to booting Xen:

sudo sed -i 's/GRUB_DEFAULT=.*\+/GRUB_DEFAULT="Xen 4.1-amd64"/'
/etc/default/grubsudo update-grub

Set the default toolstack to xm (aka xend):

sudo sed -i 's/TOOLSTACK=.*\+/TOOLSTACK="xm"/' /etc/default/xen

Now reboot:

sudo reboot



But when rebooting the Dom0 failed to start, enclosed was the error message
when Xen booting and after that Dom0 will restarting over and over.
On Blade server system  log I got error message :
(Bestak_septaher) SMI Hdlr: 00151743 HI Fatal Error, HI_FERR/NERR Value=
0020
(Bestak_septaher) Critical Interrupt - Front panel NMI

Please Suggest, thank you very much for any one help.

Best Regards,

Agya

- What exact Xen version are you using? 
- What exact Linux dom0 kernel are you using? 
- Please paste your grub settings for the Xen entry.
- Did you capture the error/crash logs from the Serial console? (SOL provided by the blade management).

Arrfab (CC'd) is actually seeing a similar problem on IBM HS20 blade with Xen 4.2.1 
with Linux 3.4.28 dom0 kernel.

Does this ring anyone's bells?

Which doesn't even include the message in the subject afaics, so I
don't even know what you're talking about. And the other, earlier
report has no useful information either.

From an abstract perspective, a front panel NMI to me would mean
someone pressed an NMI button on the system's front panel. You
don't think Xen can do anything about this, do you? And even if
the NMI has another origin, it's still a hardware generated event
that Xen has no control over.

Arrfab said Xen crashes and reboots in the middle of the boot process,
and the blade chassis management logs the NMI error. The user is not pressing (NMI) buttons.

The serial log included is everything he gets. No error visible in the serial log,
only a crash/reboot without any errors.. No idea what could be causing that.. 

The same Dom0 kernel (pvops 3.4.28) boots OK on baremetal without Xen.

Do you have any Xen and/or dom0 kernel options to use to do further analysis?

Even with the IOMMU fully enabled?

I don't recall if sync_console was used - if not, it should be.

And of course the inverse of the above - turning the IOMMU off -
should be tried in Xen.

Thank you Pasi to forward this email for me too, it seem not only me facing
this problem. I found this guy also found similar problem, its in french
but we can translate it easily using google
http://debian.2.n7.nabble.com/Probleme-XEN-4-0-1-et-SQUEEZE-64bits-reboot-td1230690.html

I found parameter nmi=ignore | dom0 | fatal

nmi=reaction : Enables you to specify how the hypervisor reacts to a non -
maskable interrupt
(NMI) resulting from a parity or I/O error. Possible values for reaction
are fatal (the hypervisor
prints a diagnostic message and then hangs), dom0 (send a message to
domain0 for logging
purposes but continue), and ignore (ignore the error). If you do not
specify this option, Xen
uses the default value dom0 internally.

But its still doesn't work on my machine.

Re: IBM HS20 Xen 4.1 and 4.2 Critical Interrupt - Front panel NMI crash

[agya naila]

[-- Attachment #1.1: Type: text/plain, Size: 3344 bytes --]

As I read on IBM paper :

When a non-maskable interrupt (NMI) signal is received, the processor
immediately drops what it was doing and attends to it. The NMI signal is
normally used only for critical problem situations, such as serious
hardware errors This setting is Enabled by default. When an NMI is issued
by a critical event the BMC performs the system to reset for recovering the
system. The BMC logs the reboot and additional error events in the SEL.

I dont know why XEN trigger or cause this NMI signal, since when I boot the
machine with the same Operating system Ubuntu 12.04.1 Desktop 64 bit
without XEN its run perfectly. One more interesting fact with the same Dom0
with excacly the same XEN version and configuration running perfectly on my
notebook Toshiba Satelite L735 Intel I5, Hopefully anyone have solution for
the server.

So you tried adding "nmi=ignore" for xen.gz in grub settings and it didn't help? 
Did you try the other possible values?

I configure it by added nmi=ignore to my /boot/grub/grub.cfg

### BEGIN /etc/grub.d/20_linux_xen ###
submenu "Xen 4.1-amd64" {
menuentry 'Ubuntu GNU/Linux, with Xen 4.1-amd64 and Linux 3.2.0-29-generic'
--class ubuntu --class gnu-linux --class gnu --c$
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos1)'
        search --no-floppy --fs-uuid --set=root
730a0f5f-4c35-4391-b760-0b6cf0cdd6a7
        echo    'Loading Xen 4.1-amd64 ...'
        multiboot       /boot/xen-4.1-amd64.gz placeholder noreboot
dom0_mem=1024M nmi=ignore
        echo    'Loading Linux 3.2.0-29-generic ...'
        module  /boot/vmlinuz-3.2.0-29-generic placeholder
root=UUID=730a0f5f-4c35-4391-b760-0b6cf0cdd6a7 ro rootdelay=180 q$
        echo    'Loading initial ramdisk ...'
        module  /boot/initrd.img-3.2.0-29-generic
}

And its doent work

Just to add that I also tried the nmi=ignore parameter for Xen, and it
stills hard reboot/resets automatically during the kernel dom0 boot

Hello all,

Today Xen finally running on IBM blade server machine, try to add nmi=dom0
and find the Base Board Management Controller on bios configuration and
disabled the 'reboot system on nmi' attribute. This step won't eliminate
the nmi problem since I still found NMI error interrupt on my blade server
log but xen would ignored and keep running. If any other found better
solution would be great.

Thanks for the 'workaround' info.

We still should find out what exactly generates/causes that NMI with Xen..
