virtio network device trashes udp packages > 1KB

Priority: major Component: network/hostif
Version: VirtualBox 4.1.0 Keywords:
Cc: Guest type: Linux
Host type: Linux

Description

diagnostic from the host:

[34958.661066] UDP: short packet: From 192.168.202.42:56681 53253/1488 to 192.168.202.1:1234

test case for the guest attached. sends one package with either 1KB or 4KB. the 1KB package comes through fine, while the 4KB package is being dropped by the host.

This can only be reproduced with virtio network adapters. emulated ones work fine.

Host and guest kernel are 2.6.39.1 and 2.6.39.3
