Description Mohammad Mateen 2009-08-28 13:37:57 UTC

Description of problem:
KVM based Guest VM become halt after huge data rsync

Version-Release number of selected component (if applicable):


How reproducible:
Just rsync more then 15G data from any live host.

Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:


Additional info:

I have am using FC11 64bit on Host and same OS on KVM based guest machine. I am using TAP based routing network inside host. I am using virtio network driver for my guest machine

When i transfer huge data via rsync from another live host my guest machine got halt with following errors in log. I need to restart network service to make guest VM back.

With 512M RAM for guest VM, it got halt for 5G data transffer via rsync
With 1G RAM  for guest VM, it got halt if  i try to shift 15G data transffer via rsync

Comment 1 Mohammad Mateen 2009-09-02 12:49:50 UTC

i got the same error with new kernel and on different VM. Problem always occur while doing rsync, though data transfer size is not too big.

i am using following CPU. Plz let me know if u need more details.

vendor_id	: AuthenticAMD
model name	: AMD Athlon(tm) 64 X2 Dual Core Processor 5200+


Regards

Comment 2 Mark McLoughlin 2009-09-04 12:19:48 UTC

bug #480822 was a kinda similar looking bug which was fixed before 2.6.29 was released

This thread:

  http://www.mail-archive.com/kvm@vger.kernel.org/msg14432.html

suggests it may be due to OOM

This looks like it might fix it:

Comment 3 Mohammad Mateen 2009-09-07 19:05:37 UTC

For testing purpose i have remove virtio driver from my VM Conf and then try to do rsync from 3 different location have 4G, 4G and 7G of Data simultaneously. 

At last i got the same error with standard driver.

will you say it still virtio_net failure ?

Comment 4 Mohammad Mateen 2009-09-07 19:08:54 UTC

I more thing i forget to mention, my machine never goes to swap


Regards, Mateen

Comment 5 Mohammad Mateen 2009-09-07 19:24:19 UTC

Sorry forget to mention another imp point. VM got in working and dont become halt on standard driver, just give above mentioned errors in logs again & again almost 50 times until rsync finish.

--------------
grep 'swapper: page allocation failure' /var/log/messages |wc -l
50
--------------

The fix suggested above is related to following error:-

"[929492.154634] pdflush: page allocation failure. order:0, mode:0x20"

while i am getting different error:-

"phili-p kernel: swapper: page allocation failure. order:0"

I think its pure kernel issue. 


Regards, Mateen

Comment 6 Mohammad Mateen 2009-09-14 19:53:02 UTC

Any update on the issue ? 

For kind information i got the same errors on FC10 based VM's as well.

i have opened a new bug for FC10. See

https://bugzilla.redhat.com/show_bug.cgi?id=523299

Comment 7 Mark McLoughlin 2009-09-21 12:51:03 UTC

Mohammad: could you try and reproduce with the 2.6.30 kernel in F11 updates? Thanks

Comment 8 Mohammad Mateen 2009-09-24 12:20:17 UTC

Here is what i am getting new kernel and fedora default network driver with tap networking:

backport of 2.6.31 virtio_net patch

Okay, I think the best thing is to try this virtio_net patch from 2.6.31

It certainly looks like it should fix the issue

Justin, could you apply this? I've backported it, but haven't even tried compiling it

Comment 10 Justin M. Forbes 2009-10-02 20:44:58 UTC

Tested and applied, it should appear in the next F-11 update kernel.
