Title:
Broken networking in kvm guests with pcnet driver
Status in bridge-utils package in Ubuntu:
Invalid
Status in linux package in Ubuntu:
Won't Fix
Status in qemu-kvm package in Ubuntu:
Won't Fix
Bug description:
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.
