Any chance you could post it raw (cpuid -1 -r)?

Thanks.

Bug description:
  Memory Bandwidth Monitoring (MBM) is a CPU feature included in the family of 
Platform QoS features.  It is used to track memory bandwidth usage for a 
specific task, or group of tasks.
  Memory Bandwidth Monitoring is an extension of the existing Cache QoS 
Monitoring (CQM) feature found in Haswell server.  The mechanism used is the 
same, where tasks are associated with an Resource Monitoring ID (RMID), which 
the CPU uses to track the bandwidth usage.

Can you post guest's cpuid -1 -r ? (I guess after you verify Thomas' patch)

Thanks.

  This allows the ballooning to be cancelled if adding new memory failed which 
means that the error message is printed once instead of repeatedly.

  There should still be effort to root cause this issue and determine

I was waiting for this patch to be pulled into the mainline before
posting a pointer/commitID here. It's not there yet.

But yes, you need that commit (on top of 3dcf63677d4e) to make kernel

Hmm, yes, the patch may not work if something (AWS, I guess) keeps
requesting to balloon memory.

Can someone try the attached patch (on top of David's)? I only compile-
tested it.

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

Actually, this (v2) is a slightly better one to try.

Bug description:
  SRU Justification:
  [Impact]
  The following errors may occur on HVM instances on EC2: xen:balloon: 
reserve_additional_memory: add_memory() failed: -17

  [Test Case]
  Boot Ubuntu Trusty 3.13 series HVM instances and check dmesg for this error 
message.

  [Fix]
  A minimal fix for this bug can be found here:
  
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3dcf63677d4eb7fdfc13290c8558c301d2588fe8
  This allows the ballooning to be cancelled if adding new memory failed which 
means that the error message is printed once instead of repeatedly.

  There should still be effort to root cause this issue and determine
  how to avoid the ballooning errors in the first place. I still think
  this patch should be applied to alleviate symptoms until root cause is
  discovered.

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

[Boris Ostrovsky]

I am not sure the bug should be closed. David's fix made system behavior
tolerable to users (because the error is now only reported once) but the
problem is still there. If possible I'd suggest lowering bug's priority
but keeoping it open.

No fix (from me, that is)

I need to be able to reproduce this and this appears to only be
happening in AWS environment.

Matt, can you post config file that you used? I tried a few different

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

[Boris Ostrovsky]

So given that you are seeing this on 3.2 guest this would be a different
problem. Having said that, I don't see any errors in dmesg_domu.txt
anyway.

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

[Boris Ostrovsky]

If you don't specify debug and loglevel boot options I think you won't
see these. Of course, the underlying problem would still be there.

Do you observe this on guests with newer kernels?

[Boris Ostrovsky]

Can you please post:

1. Guest configuration file
2. boot log from dom0 (please boot loglevel=8)
3. xl dmesg and xl info from dom0
4. boot log from guest (also loglevel=8)
5. dmidecode from guest (I am mostly interested in BIOS object)

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

[Boris Ostrovsky]

Yes, those would be helpful although now I think understanding EC's BIOS
(seabios I assume?) may be more important. Neither I nor Stefan have
been able to reproduce this problem and it seems that EC does something
in BIOS (and possibly qemu) that may not be available in vanilla Xen,
most importantly building ACPI tables for guests (which is where memory
is desribed). I, for example, would like to know how SRAT is generated.
I don't think this can be done by config file alone.

We may need to get Amazon folks involved.

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

[Boris Ostrovsky]

This warning implies that SRAT may be wrong. And I just noticed that this may 
not be vanilla 4.2:
 [0.00] DMI: Xen HVM domU, BIOS 4.2.amazon 01/24/2014

Are we on a custom HVM BIOS? That's where memory is described to domain.

Although NUMA issue may be somewhat orthogonal, it still may be worh
looking at. Andrew, can you do this on booted guest:

   acpidump  acpi.dat
   acpixtract -a acpi.dat
   iasl -d srat.dat

and post here srat.dsl

And again, seeing guest config file would be important.

[Kernel-packages] [Bug 1304001] Re: xen:balloon errors in 14.04 beta

[Boris Ostrovsky]

I would like to reproduce this first and for that I will need at least
config file that is used for launching the guest ('memory' and 'maxmem'
for sure but having the whole file would be better) as well as guest's
kernel config file. Knowing what xen boot options are as well as if
there is anything interesting in /etc/xen/{xl.conf|xend-config.sxp}
may also be helpful.

But seeing debug output definitely won't hurt. In fact, add 'debug
loglevel=8 memblock=debug' to boot line for good measure (I hope it
won't be too much output).
