Addendum to the above - it's been pointed out to me that scp DOES trigger the bug for you, so I was completely unable to reproduce your bug.
My setup however was using the 0.12.5 kvm listed above, as well as the lucid pre-proposed kernels from https://launchpad.net/~kernel-ppa/+archive/pre-proposed. Can you please re-test with those? If the bug is fixed with those, then please let us know which fixed it - kernel drivers or updated qemu. If the bug persists, then I'd hazard the culprit is something else in your environment (a misbehaving switch, or even some ne'erdowell software on the host, though that is unlikely) because I think I've completely reproduced your settings. ** Changed in: qemu-kvm (Ubuntu) Status: Confirmed => Incomplete -- Broken networking in kvm guests https://bugs.launchpad.net/bugs/616064 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
