Brain Fallik, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest server
release of Ubuntu? ISO images are available from
http://releases.ubuntu.com/raring/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications-Accessories-Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux replace-with-bug-number
Also, could you please test the latest upstream kernel available following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Please do not test the daily folder,
but the one all the way at the bottom. Once you've tested the upstream kernel,
please comment on which kernel version specifically you tested. If this bug is
fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For
example:
kernel-fixed-upstream-v3.11-rc5
This can be done by clicking on the yellow circle with a black pencil icon next
to the word Tags located at the bottom of the bug description. As well, please
remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Binary package hint: qemu-kvm
-
Some TCP operations receive unexpected reset (RST) packets when executed on
the guest. I can see these RST packets via
Wireshark but can't explain their source. This breaks certain (most)
networking on the guest.
I uncovered this when some 'git clone' operations failed with Broken
Pipe in the guests. I've been able to reproduce the same failures
using scp and 'svn checkout'. The failure occurs 80-90% of the time and
'svn checkout' seems to be the quickest to fail. The same operations on
the host are always successful.
My setup is a Lucid amd64 host with two guests (Lucid and Hardy, both
i386, using kvm). Networking seems to mostly work. I can maintain
persistent ssh connections to the guest and some networking operations
from the guest (ie. ping) never fail. However, the git-clone/scp/svn-
checkout operations fail almost all the time. I've tried this with both
virtio and e1000 drivers with no difference.
This may be similar to some of the behavior reported in bug 584048 but
not the final patch referenced in comment 27. I built a custon deb
including the upstream patch for testing and it had no effect.
