Subject: Latest Stretch qemu-system-i386 process balloons in Xen Dom0 RAM, crashes DomU

Date: Thu, 10 Aug 2017 14:45:56 -0400

[Message part 1 (text/plain, inline)]

Package: qemu-system-x86Version: 1:2.8+dfsg-6+deb9u2
Problem:======Latest Stretch `qemu-system-i386` process consumes the
majority of Xen Dom0's RAM, ultimately crashes DomU.
Symptoms:========When starting a Xen HVM guest with qemu-system-x86
version 1:2.8+dfsg-6+deb9u2 installed, the `qemu-system-i386` process's
CPU usage is high and its RAM balloons to consume up to 75% of Dom0's
RAM. This makes Dom0 extremely sluggish and forces Dom0 to page out to
its swap partition.
Watching the DomU boot via its virtual serial console, it hangs at the
"loading initial image" portion of Linux's bootstrap for far longer
than normal.
Dom0 CPU usage normalizes at around 4% once the DomU has finished
booting, but the process's RAM usage does not decrease. If left
running, the DomU ultimately dies. Using `xl list`, the DomU's state
prints as "------".
At this point, the DomU can only be destroyed. Killing the DomU with
`xl destroy` yields:
libxl: error: libxl_dm.c:2303:kill_device_model: Device Model already
exited
What I've tried:==========- Commenting out all but essential lines from
the DomU's config file,- When commenting out all storage and starting
the DomU, qemu-system-i386's resource utilization remains fine with the
DomU boot-looping at the SeaBIOS. Booting from any kind of storage
causes the issue.
Workaround:
=========
Downgrading back to qemu-system-x86 1:2.8+dfsg-6 resolves the issue.
Setup:====- OS: Debian Stretch, all packages up to date as of 10
August, 2017- Architecture: 64-bit Intel x86- Hypervisor: xen-
hypervisor-4.8-amd64 (4.8.1-1+deb9u1)- QEMU package: qemu-system-x86
(1:2.8+dfsg-6+deb9u2)- Kernel (Dom0 and DomU): linux-image-4.9.0-3-
amd64 (4.9.30-2+deb9u3)- RAM allocated to Dom0: 512MB (ballooning
disabled)- Physical CPU cores allocated to Dom0: 4 of 4
Steps to reproduce:=============1. Set up the Dom0 system with latest
packages for Debian Stretch,2. Create a generic HVM DomU configuration
file (default HVM builder, default device_model_version),3. Start the
HVM DomU with `xl create`,4. Monitor qemu-system-i386 CPU, RAM usage
with `top.`

Hello,

I can confirm this bug.
Xen dom0 balloons endlessly and consumes all swap.
Then dom0 kills one domU after another.
Downgrading to qemu-system-x86 1:2.8+dfsg-6 helps solving the problem 
for me too.
Same system with KVM is not affected.

I think the severity of this bug is very high. Any server upgraded to 
latest stable version of Debian system using Xen having Domu (pv not 
affected) will stop to work.

Does this happen with version 1:2.8+dfsg-6+deb9u1 too?
Does this happen with qemu-system-x86_64?

Both of these versions include the same patch from upstream, but a
bit different incarnations of it. I suspect that both are having
probs here.

Please note that -i386 version (32bit) isn't being often tested these days,
most development/testing is done with -x86_64 version, so please switch to
the -x86_64 version if that works.

Due to the same reason, I don't see why severity of this bug should be
raised, -- if it were actually not working with 64bit version of qemu,
it'd be quite noizy due to all xen users complaining.

Still, it'd be nice to find and fix the issue.

Thanks,

That's a good question. I did not see that version of the package
available in `apt-cache` when I performed my rollback, so I cannot say.

> Does this happen with qemu-system-x86_64?

The architecture being run *is* 64-bit. As I understand it, Xen uses
its own i386 adaptation of Qemu for its HVM domUs, hence the "-i386" in
the process name.

Hi!

I can confirm this bug and indeed it happens with "qemu-system-x86_64" on 1:2.8+dfsg-6+deb9u2, too.

However, it does *not* happen using 1:2.8+dfsg-6+deb9u1! I have not tried it for a longer time but the memory consumption is a lot better immediately if I go back to 1:2.8+dfsg-6+deb9u1.
On 1:2.8+dfsg-6+deb9u2, my Windows 7 x64 VM used 4GiB of Dom0 during setup and at least 1GiB for "normal operation" (slowly growing).
Now, using 1:2.8+dfsg-6+deb9u1, QEMU consumes about 40MiB of Dom0 which is a lot better.

Hope this helps to narrow down the issue.

Actually we've found the issue, see https://bugs.debian.org/871648#52 -
somehow I missed this back in Aug when this email arrived - I was quite
a bit busy at that time.

I already asked for an update for -stable with these changes and with
other security fixes, so this bug should hopefully be fixed soon.

Thank you!

No, it doesn't happen in this version. Everything works in this version.

Yes, using the x86_64 emulator doesn,t change anything.


The problem is in the upgrade of the package : 1:2.8+dfsg-6+deb9u2
(source: qemu 1:2.8+dfsg-6+deb9u2)

I get this error on using qemu/qcow2 as storage driver :
"libvirtd: 4266: error : libxlDomainBlockStatsGatherSingle:5481 :
Operation not supported: unsupported disk driver qemu"

This error is not present in version 1:2.8+dfsg-6+deb9u1.

No, I think not. Will retest and report back.

The problem I use i386 is that Debians 64bit-Xen package is compiled 
with...

		./configure \
			--disable-docs --disable-stubdom --disable-xen \
			--prefix=/usr \
			--includedir=/usr/include \
			--libdir=/usr/lib/$(DEB_HOST_MULTIARCH) \
			--mandir=/usr/share/man \
			--infodir=/usr/share/info \
			--sysconfdir=/etc \
			--localstatedir=/var \
			--with-libexec-leaf-dir=xen-$(VERSION) \
			--disable-blktap1 \
			--disable-blktap2 \
			--disable-ocamltools \
			--disable-qemu-traditional --disable-rombios \
			--with-system-qemu=/usr/bin/qemu-system-i386 \
			--with-system-seabios=/usr/share/seabios/bios-256k.bin

I use Ganeti with Xen and have configured my cluster to use x86_64 but 
no chance > Xen always starts i386 qemu.
The last years I was recompiling Xen because of this, but gave up some 
months ago. Doing this on every update made me go nuts.

Will recompile and report back soon.

In the meantime I did some more tests and updated Xen to 4.8.1-1+deb9u3 
> no change.

But I've found out, that this problem only happens when I start a 
"Windows 2008 r2" instance on the host. Maybe "Windows 7" triggers the 
same problem?!.
As long as I only start "Windows 2012 r2" or "Windows 8.1" the problem 
does not occur.
Updating the PV drivers inside Windows 2008 r2 instance from 8.1.0 to 
8.2.0 did not help.

Dear all,

Unfortunately, we are experiencing this with linux guests also. And with 
deb9u1 this works fine.

Now that qemu-system-x86 1:2.8+dfsg-6+deb9u3 has been released, I have
upgraded and tested.

So far, so good! The CPU and RAM utilization of the `qemu-system-i386`
process seems very normal: ~4% CPU usage and ~9% RAM usage. The HVM
domU is booted and active. If it goes comatose again, I will let
everyone know but, preliminarily, it looks like the upstream fix
worked.
