Hi,
after adding the 'device_model_stubdomain_override = 1' to an otherwise
fine configuration the domain crashes on start.
Xen is v4.6.1 compiled from source on Debian Jessie 64bits this way:
- ./configure --enable-stubdom --enable-githttp
- make dist-xen
- make dist-tools
- make dist-stubdom
- make install-xen
- make install-tools
- make install-stubdom
As pointed out before the same configuration file without the '
device_model_stubdomain_override' works flawlessly.
This is the 'xl list' command output while the domain is starting:
Name ID Mem VCPUs State Time(s)
Domain-0 0 1022 2 r----- 318.3
win7-sp1-x64-2 20 2048 1 r----- 5.5
win7-sp1-x64-2-dm 21 44 1 r----- 6.0
As you can see both domains are started (the stub and the original domain)
Find attached the domain configuration file, 'xl info' output, 'xl create'
output and the /var/log/xen/console/hypervisor.log file, notice the grant
table error on console-hypervisor.log
I'd very grateful for any help finding the cause of this problem.
Best regards,
Fanny

The hypervsior log show some error, but unfortunately it is not
immediately clear what went wrong.
Do you have a working base line setup so that I can compare the
difference?

Hi Wei,
first: thanks for your effort. :)
Find attached the 'xl create' output and the
/var/log/xen/console/hypervisor.log
files after creating the same domain without the
'device_model_stubdomain_override' configuration option.
'xl list' command output...
Name ID Mem VCPUs State Time(s)
Domain-0 0 1023 2 r----- 11608.1
win7-sp1-x64-2 28 2048 1 ------ 0.4
Regards,
Fanny

I was hoping that you somehow had a running setup with stubdom enabled.
Have you tried earlier version of Xen or is this your first attempt to
use stubdom?

I'm sorry but this is my first attempt to use stubdom.
This is a test machine so feel free to propose xen recompilation adding
printk's/obscured options or settings modification.
With regards,
Fanny

Sorry for the late reply.
In the case successfully booting DomU, do you see similar error like
this in xl dmesg?
(d21) read error -1 on /local/domain/21/device/vbd/768 at offset 0, num bytes 512
(XEN) grant_table.c:525:d0v0 Bad flags (0) or dom (0). (expected dom 0)

Another thing to try is to add to your config without
device_model_override=xxx,
device_model_version="qemu-xen-traditional"
and see if it still works.
Here is why: the default device model is upstream qemu, but when you
need to use stubdom, the device model is another version of qemu
(qemu-trad). The newly added config option forces Xen to use the same
qemu that would be used when stubdom is in use. It's useful to figure
out if qemu-trad is not functioning.

This reminds me of a bug that would cause error in disk:
http://lists.xen.org/archives/html/minios-devel/2016-04/msg00000.html
Are you able to apply the patch in that thread and test?
For your convenience I've attached the patch. It needs to be applied to
xen.git/extras/mini-os.

Subject: [PATCH] Mini-OS: netfront: fix off-by-one error introduced in
7c8f3483
7c8f3483 introduced a break within a loop in netfront.c such that
cons and nr_consumed were no longer always being incremented. The
offset at cons will be processed multiple times with the break in
place.
This commit reverts to using the "some" variable in the loop condition,
but avoids ifdefs for the non-libc case. It also renames it to dobreak
to make its usage clearer.

Wei,
It works now!
Many, many thanks for your invaluable time.
By the way, Do you know when the patch will be included in the stable-4.6
branch? Maybe will be on time for the 4.6.2 version?
IMHO is an important patch because of the added security shielding it
provides (allowing the use of stub domains on some cases).
Best regards,
Fanny

Yes, it's on my radar. I hope to get it committed to xen-unstable soon.
And then it will need to wait a bit to land in 4.6.2.
Thanks for testing.
Wei.

Wei, thanks for your help.
After following your advice I added to the DomU config the
'device_model_version = "qemu-xen-traditional"' (and removing
'device_model_stubdomain_override'), the DomU started successfully as
without stub domain:
(d18) Press F12 for boot menu.

(d18) Booting from Hard Disk...

(XEN) irq.c:275: Dom18 PCI link 2 changed 11 -> 0
(XEN) irq.c:275: Dom18 PCI link 3 changed 5 -> 0
Just for the sake of remember this is the log of the DomU with the initial
configuration (no 'device_model_version' and no
'device_model_stubdomain_override'):
(d19) Press F12 for boot menu.

As you can see the error message appears only with the stub domain config.
