Hi,
I have configured Xen to boot directly from EFI (with `efibootmgr`).
As explained on the Xen_EFI wiki page, I have added a line "options="
into my file "/boot/efi/EFI/xen/xen.cfg" :
```
# cat /boot/efi/EFI/xen/xen.cfg :
[global]
default=xen
[xen]
options=dom0_mem=1G,max:1G
kernel=vmlinuz root=/dev/md2 ro rootdelay=10 noquiet nosplash
ramdisk=initrd.img
```
With the line `options=dom0_mem=1G,max:1G` the server reboot infinitely.
Without the line `options=dom0_mem=1G,max:1G`, the server boot
correctly, but obviously, the dom0 memory is in ballooning mode.
I have attached a screen shot of the boot lines with the last lines I
can see before the reboot. Unfortunately, I have nothing in kern.log.
1. Do you know what happens ?
2. Do you need some logs ?
Regards,
Guillaume

Of course there's nothing in a log on disk - the crash occurs way to
early. Yet you'll need to provide the kernel messages, either via
serial console (and "earlyprintk=xen") or some other means, in
order for anyone to be able to tell/guess where the problem might
be.

I attached a console log "xen-console-log.txt".
Here, Xen crash even without the "dom0_mem=1G,max:1G" option :
```
# cat /boot/efi/EFI/xen/xen.cfg
[global]
default=xen
[xen]
options=loglvl=all com1=115200,8n1 console=com1,vga
kernel=vmlinuz root=/dev/md2 ro rootdelay=10 noquiet nosplash
earlyprintk=xen console=com1
ramdisk=initrd.img
```
Do you need something else helpful ?
Regards,
Guillaume

Xen doesn't crash at all. It's the Dom0 kernel which panics, but
the log doesn't tell me why it does (other than _something_
having tried to exit the init process). This doesn't look Xen related
at all with the provided information.

With this file, it works, Xen boots :
```
[global]
default=xen
[xen]
options=loglvl=all com1=115200,8n1 console=com1,vga
kernel=vmlinuz root=/dev/md2 ro rootdelay=10 noquiet nosplash
earlyprintk=xen
ramdisk=initrd.img
```
With this file, I have just added "dom0_mem=1G,max:1G", Xen crashes :
```
[global]
default=xen
[xen]
options=loglvl=all com1=115200,8n1 console=com1,vga dom0_mem=1G,max:1G
kernel=vmlinuz root=/dev/md2 ro rootdelay=10 noquiet nosplash
earlyprintk=xen
ramdisk=initrd.img
```
I attached the boot logs "dom0_crash_with_dom0_memory.txt". The last
line is "(XEN) Hardware Dom0 crashed: rebooting machine in 5 seconds."
Do you need something else helpful ?

... this line you observe. Taking further lines from the log you've
provided subsequently:
(XEN) d0v0: unhandled page fault (ec=0003)
This tells us that Dom0 didn't install a page fault handler yet.
(XEN) Pagetable walk from ffffffff82565200:
(XEN) L4[0x1ff] = 000000084600e067 000000000000200e
(XEN) L3[0x1fe] = 000000084600f067 000000000000200f
(XEN) L2[0x012] = 0000000846647067 0000000000002647
(XEN) L1[0x165] = 0010000846565065 0000000000002565
This tells us (together with the page fault error code) that the
Dom0 kernel tried to provide memory as kernel stack which
can't be written. This may be a Dom0 kernel stack overflow,
but there may also be other reasons. At this point I can't
exclude there being some root cause in Xen, but the issue
needs to be investigated from the Dom0 kernel side.

# About the kernel crash
> Did you read the above?
I just wanted to say that I have solved the kernel panic crash that I
had before, when you explained "Xen doesn't crash at all. It's the Dom0
kernel which panics".
Just for information the crash happens if I put the "console=com1" to
the kernel command line.
```
kernel=vmlinuz root=/dev/md2 ro rootdelay=10 noquiet nosplash
earlyprintk=xen console=com1
```
And this, I understand, is not linked to Xen.

I have tested with the version 4.9 and 4.14 of the kernel from Debian
and the crash occurs when there is the option "dom0_mem=1G,max:1G".
https://packages.debian.org/stretch/linux-image-amd64
https://packages.debian.org/stretch-backports/linux-image-amd64
Do you want that I test something else ?

Guillaume

Really? Why do you think this is related to the stack?
The error code just tells us it was a write access. %rsp is
ffffffff82003cb0, while %cr2 is ffffffff82565200.
To me it seems as if the access was via %rbx.
It would really help to know which function caused the access. As the
stack contains some parts of the last messages issued I suspect this
is related to EFI code.

So having a more readable backtrace would really help.
Guillaume, can you try to get symbol+offset for the values on the stack
looking like kernel code addresses (e.g. everything starting with
"ffffffff82")?

For sure. Just, can you explain me how I can do this, please ?

Oh, I didn't look very closely. It's just a common pattern of stack
overruns. In any event I've said "may" for a reason.

You'll need a decompressed kernel with symbol information in it. On my
system (SUSE) I have a vmlinux.<version>.bz2 for each vmlinuz.<version>
file installed in /boot. Use this kernel file and the "addr2line" tool
(to be found in binutils package):
addr2line -pfi -e vmlinux.<version> <addr> <addr> <addr>
e.g.:
addr2line -pfi -e vmlinux-4.4.103-default ffffffff8160ec4d
ffffffff8160ce50 ffffffff8160e568

[-- Attachment #1: Type: text/plain, Size: 528 bytes --]
I have installed `linux-image-amd64-dbg` and `binutils`.
I can now execute `addr2line -pfi -e vmlinux-4.14.0-0.bpo.3-amd64 <addr>`.
I have generated a file "commands.txt" with all the addresses after
"Guest stack trace from rsp=ffffffff82003cb0:" in my log file
"dom0_crash_with_dom0_memory.txt".
I attached the result : "result.txt".
We can see inside this file "xen/mmu_pv.c:1548" and
"drivers/firmware/efi/efi.c:558", so I hope it will be helpful.
Is that ok for you ?
Can I do something more ?
Regards,
Guillaume

Hi Jan, hi Juergen,
I'm trying again this week to install Xen on a OVH server
(https://www.ovh.com/fr/serveurs_dedies/infra/1801eg02.xml).
It is still impossible to boot Xen with the option "dom0_mem=1G,max:1G"
(boot : EFI->xen).
I have tried with Debian 9 stable/stretch :
- grub2 (2.02~beta3-5+deb9u1) : https://packages.debian.org/stretch/grub2
- xen-system-amd64 (4.8.4+xsa273+shim4.10.1+xsa273-1+deb9u10) :
https://packages.debian.org/stretch/xen-system-amd64
- linux-image-amd64 (4.9+80+deb9u6) (4.9+80+deb9u6)
https://packages.debian.org/stretch/linux-image-amd64
I have tried with Debian 10 testing/buster :
- grub2 (2.02+dfsg1-8) : https://packages.debian.org/buster/grub2
- xen-system-amd64 (4.11.1~pre.20180911.5acdd26fdc+dfsg-5) :
https://packages.debian.org/buster/xen-system-amd64
- linux-image-amd64 (4.18+99) :
https://packages.debian.org/buster/linux-image-amd64
# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 158
model name : Intel(R) Xeon(R) CPU E3-1270 v6 @ 3.80GHz
stepping : 9
microcode : 0x8e
Microcode version seems to be up to date :
https://www.intel.com/content/dam/www/public/us/en/documents/sa00115-microcode-update-guidance.pdf
Here is my WORKING xen.cfg file :
```
[global]
default=xen
[xen]
options=smt=on
kernel=$VMLINUZ_NAME root=/dev/md3 ro rootdelay=10 noquiet nosplash
ramdisk=$INITRD_NAME
```
Here is my FAILING xen.cfg file (with dom0_mem=1G,max:1G) :
```
[global]
default=xen
[xen]
options=smt=on dom0_mem=1G,max:1G
kernel=vmlinuz root=/dev/md3 ro rootdelay=10 noquiet nosplash
ramdisk=initrd.img
```
For information, if helpful :
- Booting Linux with EFI->grub->Linux works fine.
- Booting Xen with EFI->grub->Xen fails too (In January I only had 1/8
core available, now I cannot boot but I will discuss this problem in
another thread).
Do you have more information on the dom0_mem argument problem ?
Best regards,
Guillaume

I'm sorry to say so, but nothing has changed from the prior
situation: This needs to be investigated from the kernel side
(which I'm afraid I simply don't have the time to help with).
I also have to admit that your way of stripping all relevant
(technical) context from the earlier conversation made it
necessary to dig out the old thread to understand at all what
this is about.
Jan

Hi Jan, hi Juergen,

If someone can lead me, I can give some of my time to help.
I can also provide an access to a server where the problem occurs.
Let me know what I can do.

Sorry, for everyone else interested by the problem, the thread is here :

Thanks for your reply,
