OK, that's news to us - we haven't seen any problems.

It's been tested with dd's and kernel builds, and wasn't expected to be
a particularly dangerous change.

How you confirmed that disabling the option fixes your problems? Can you
give a simple recipe to provoke problems?

It doesn't seem to be destablizing, at least for us. Possibly there's
been some feature interaction with later checkins. 

Anyone using the unstable tree should be reading the changelog

Unstableness in grant table block drivers

[Anthony Liguori]

We've experienced a lot of problems in the new grant table-based block
drivers.  It's exposing itself in a number of ways.  I've seen it stop
working after working for a bit, sometimes XenU stops half-way through
boot, and on one system init panics because it can't find a root
filesystem.

Grant table block drivers are now the default config option in
xen-unstable even though it's marked as experimental.  Perhaps it should
not be default until it gets a bit more stable?

I know the last week's been really busy, but in the future, it would be
nice if a big destabilizing change like this could get announced on
xen-devel so we could be on the look out for these sort of bugs.

Have you made any progress in further identifying or narrowing down 
these bugs? Detailed bug reports or, better, patches, are always more
useful than general reports of issues.

We've not seen any bugs ourselves but obviously if it's biting you 
regularly then may be worth while disabling in your config. I'm 
loathe to disable it by default in the general config since this 
won't help us uncover and fix whatever bugs are present.

Sure, good point (though as mentioned above, we hadn't seen any 
problems ourselves -- we strongly appreciate the community effort
in helping us ensure new changes work on a broad range of configs 
and usage scenarios).

We've had three different systems lose the ability to start domUs.  
Disabling VBD grant tables fixed the problem.  The best reproducable 
example we have is default config on a domU from today's xen-unstable 
snapshot.  /dev/console is not accessible and no valid root is found.

In my own case, it was working fairly well and then it just stopped 
working.  It would die mid-way through boot.  Again, disabling VBD 
grant-tables fixed the problem.  I'm going to look into the problem this 
evening and see if I can get you guys a more reproducable scenario.

This is where having a bugzilla would really help out.  At this stage, I 
don't know that much but enough that I could enter something in 
bugzilla.  As I learn more, we could add more detail until there was 
enough that someone (or I) could actually fix it.

That's why I suggested just sending a note to the list.  Bugs need to be 
found and that's what xen-unstable should be for.  I'm happy to leave it 
enabled by default but wanted to let the rest of the list know that if 
they run into stability problems that might be a good place to start 
looking.

I think it is safe to say that the blkback/blkfront still have some
serious bugs to be fixed even in the absences of grant tables.
Exporting more than a couple of block devices to VMs will eventually
cause domUs to stop receiving block I/O. I hope to have time to create
a  scenario that works quicktly and with a sufficiently small
configuration that you'll be able to reproduce it there. To date I've
only tried it with a fairly large number of LUNs.

Developers using xen here periodically have to re-boot their machines
as a result. They can't reproduce it consistently (thankfully), but
they're typically only using 7-10 VBDs.

Re: Unstableness in grant table block drivers

[Christopher Clark]

Hello Anthony

First off, hands up: this was my code and I just didn't get around to
sending the mail to the list as I had enough to deal with relocating
from the UK to the US last week. The code was, however, tested under
load and working fine, and I did consider it to be ready for wider
testing in unstable.

The machines you can't get to start domUs, and symptom of not finding
the root filesystem is exactly what you'd see if your dom0 and domU
configs don't match; either both or neither need to be using grant
tables for transport. Your other issues will need more investigation,
and a reproducable scenario would be extremely helpful indeed.

Regards,

Christopher

So domUs have to have grant table support enabled if dom0 does?

Hi Christopher,

My note was more of a suggestion for the future than a complaint.  You 
guys in Cambridge move very quickly and it's hard for some of us outside 
to keep up :-)  You guys just keep churning out cool stuff.

Actually, this seems like it might be a common thread between all of our 
scenarios.  I'm using (and I assume others) a standard dom0 config file 
that has all of my hardware enabled while I just use the default config 
file for domU.

I'll try to confirm this tomorrow with the other people that were 
experiencing problems.  Perhaps I'll run a copy of fsstress too and let 
you guys know the results.

How many is a lot of VBDs?  I've done quite a bit of testing of the 
devices (with Xend and with VM-Tools) and I've found the block drivers 
to be very reliable.  I've not gone much higher than 3 or 4 VBDs for 
each domain though.

Re: Unstableness in grant table block drivers

[Kip Macy]

If I do

3 VMs x 40 iSCSI LUNs/VM x foreach (lun) dd if=/dev/zero of=/dev/xbd<n> bs=64k

iscsi ops will stop going across the wire in  2 - 3 minutes. Access to
the LUNs from DOM0 still works. I haven't had a chance to try a
smaller configuration. This is all scripted so it only takes a minute
to set up, but I'm busy trying to get FreeBSD to run (and not have
DOM0 lockup) on a recent -unstable.

Is CONFIG_XEN_BLKDEV_GRANT going to be a permanent thing or will the "!
defined(CONFIG_XEN_BLKDEV_GRANT)" code be removed at some point? IMHO,
having binary incompatibilities like this between dom0 and domU is going to
be a pain.

The config option will probably be removed at some point. It's just
there to aid debugging in case someone reported block dev problems.

In the *unstable* series you really shouldn't be relying on
compatibility between different versions of the tools, xen, or the
kernels. You should always install a complete set of binaries. In the
unstable series we reserve the right to change interfaces, and
frequently do. 

Best,
Ian

Yeah, I noticed <g>. That's cool too, I was just hoping that the config
option would be gone by the time -unstable turns into -testing, and it seems
that will probably be the case.

I build xen-unstable nightly and install it completely to my test box.
My configs between dom0 and domU are always identicle except for
priviledged domain.

> and a reproducable scenario would be extremely helpful indeed.

My scenario is building the default configs either as UP or with adding
in CONFIG_SMP.  The resule is always, dom0 will boot, domU will not.
domU fails with not finding /dev/console and no root device.

I use loopback device mounts exported as /dev/sda1.

As soon as I turn off CONFIG_XEN_BLKDEV_GRANT in dom0/U configs,
the domU boots properly.

I build with debug=y and I can generate any sort of dump or information
you need to track this down.  Let me know what you need.

Re: Unstableness in grant table block drivers

[Christopher Clark]

Kip:
Yes, domUs must use grant tables for block device access if dom0 does.
It's configuring the format of the shared rings between the front and back ends.

Ryan:
Are your issues with 2.4 or 2.6?
The least tested code is the 2.4 backend in dom0.
2.6 in dom0 should support both 2.4 and 2.6 front ends fine, though so
far I've been using partitions rather than exported loopback devices.

I'm aiming to have a working development environment by the end of the
day, and first order of business will be to reproduce these issues.

Re: Unstableness in grant table block drivers

[Christopher Clark]

Hi Ryan

OK, I've got a system I can work on now.
Could you please modify the GRANT_DEBUG and GRANT_DEBUG_VERBOSE to be
set to 1, at the top of xen/common/grant_table.c and then make a debug
build of xen.

The verbose option will slow any successful boot down to a crawl, so
you don't want to leave it on unnecessarily once things are working.

I'd like to see:
all the boot messages from xen and dom0
the same from your attempt to boot domU

If you have to option to test it on a uniprocessor box, please use
that as that would match what I'm using here.

thanks

Christopher

Indeed.  Of course, now the machine won't reboot with that option

Ouch. I just used it this morning for a tree from last night, so I

Yeah, more than likely it's something 'unique' about my aging hardware.
Thanks for the info, none-the-less.

The behavior is the same as I posted before.  I will also try on a real
UP box tomorrow as well.

Could you try without the block front end driver in dom0? Is there a
reason you need it in there?

I don't understand much about the front/back end driver stuff.  I just
take the default xenolinux configs and go with them.

Do you have a .config for dom0/domU that you want me to use?

Or at least what CONFIG_ options should be on/off for the dump?

Try "maxcpus=1"

I added it a couple of days ago.

Thanks,

Re: Unstableness in grant table block drivers

[Christopher Clark]

Anyone have ideas as to what this is in both of Ryan's Xen/dom0 output?

"ssttoop_pth_ithsis__ccppu ud diissaablbele_l_olcaolca_l_AAPPIICC

stsompp_s_ethnid_sst_opc pud diisasblea_lboclae_ll_AoPcaIl_CAPI

It doesn't look good to me.

Panic is the only thing that calls smp_send_stop, so I think the badness
has already happened.

Ryan: is this an SMP guest?

The second one is also interleaved with
"smp_send_stop disable_local_APIC".

Yes, that only shows up when trying to boot an SMP guest.

Does the crash only occur when trying to boot an SMP guest - ie. do UP
guests start correctly?

Ryan and Anthony: I've attached a patch that I'd like you to apply to
your unstable tree -- it just printk's almost everything so I can get
an idea of the code path you're running.
Alternatively, the three .c files modified by the patch are also
attached - they're taken from 2005-04-14 unstable and you should be
able to just replace the files in your tree.

After changing your tree and rebuilding, please send the console logs
from boot onwards for xen/dom0 and domU, in a uniprocessor
configuration, both with and without using grant tables for block
transport.

thanks

Christopher

No, all domU's, whether SMP or UP crash the same way.

I've applied the patch and I have a bunch of logs.

1) domU boot output when dom0up boots domUup
2) domU boot output when dom0up boots domUsmp
3) xen console output for 1) and 2) 
4) domU boot output when dom0smp boots domUup
5) domU boot output when dom0smp boots domUsmp
6) xen console output for 4) and 5) 

In the above cases, dom0up was simulated with maxcpu=1, as I still don't
have that UP box setup.  If you can't find anything in these logs then
I'll go get a real UP box and repeat the dumps.

Re: Unstableness in grant table block drivers

Many thanks for taking the traces. I've located a bug in the block
backend that may or may not be the required fix -- it's a move of a
single line, see the patch below.

Building unstable on a Debian Opteron box.

[Ray Lanza]

I'm trying to build xen on a dual Opteron running Debian (sid) and am
encountering include file conflicts.  Has anybody successfully built and run
on a configuration like this or am I into new territory?

	thanks,

I heard this once before.  It looked to me like a Debian header issue.
Do you have specifics?  (BTW, xen on dual opteron builds fine here).

I've had the patch applied and the grant table code enabled for about a

experiencing a crash every couple hours.

I'll let you know if anything changes.
