Description Charles R. Anderson 2011-02-19 12:21:22 EST
Created attachment 479710 [details] virtio-net: set size of transmitted ethernet frame to header + data length Description of problem: All ethernet frames sent by gpxe's virtio-net driver have a length of 1514, regardless of the actual size needed to encapsulate the data. This messes up at least DHCP on some networks, because the DHCP relay agent can't manipulate the "full" ethernet frame. This was causing KVM PXE failures for me since the DHCP transaction wouldn't complete. Version-Release number of selected component (if applicable): gpxe-1.0.1-1 How reproducible: always Steps to Reproduce: 1. Use virt-manager to create a VM with network driver virtio 2. Try to PXE boot the VM 3. Monitor the traffic--all frames have an ethernet length of 1514 Actual results: fail to boot via PXE Expected results: Should boot via PXE. virtio-net should set the ethernet frame length to the actual size of the data to be sent + headers. Additional info: See attached patch for the fix.

Same fix needs to be applied to F13, F14, F15, rawhide/F16, and EL5 branches. Thanks.

EL6 bug #679188 Thanks for the patch Chuck. Applied on F13-rawhide and EL5 branches now. Gonna need some testing.
