I went back and retested this and it has already been fixed and released
(commit fcbc05a1be0a7600153e78207dcb8b62fe753a4a), it was just not

mapl,
If you are running an updated hardy guest running the 2.6.24-29 kernel this bug
should not be a problem. Can you please provide

I installed Hardy as a guest on KVM on RH 5.4 using bridge networking.
System will reboot as soon as I tried to pull in a file via either ftp,
nfs or scp. Just changed back to virtual networking and the problem goes
away. This severly limits my ability to have the guest be accessed
externally.

I installed the package from proposed and it solved the problem for me.
I ran the test provided in this bug report and some file tranfers with
scp that used to crash and it worked flawlessly.

I just added a new task, triaged/high against hardy's linux kernel.
The Hardy linux kernel uses a backport of 2.6.25's virtio-net
implementation that causes this bug.
This virtio-net driver needs to be fixed such that hardy vm guests using
virtio-net doesn't truncate packets and crash
Okay, I ran these tests myself, and verified that the current package in
karmic-proposed solves the issue.
Can I get some help from someone else out there? Ideally, the original
bug reporter will be able to validate the fix. Trunet?

Accepted qemu-kvm into karmic-proposed, the package will build now and
be available in a few hours. Please test and give feedback here. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed. Thank you in advance!
