[Qemu-devel] [Bug 638955] Re: emulated netcards don't work with recent sunos kernel

[Stefan Weil]

Hi Daniel,

I just tried a newer version of the indiana iso image
(http://dlc-origin.openindiana.org/isos/148/oi-dev-148-x86.iso) with
latest qemu (not qemu-kvm) on a debian amd64 linux host, and I had no problems
with networking (ssh from qemu's emulated indiana host to physical linux host).

Tested with e1000 and i82559c, both work.

Does the error only occur with the older iso image?
Or is it caused by qemu-kvm?

Regards,
Stefan

Title:
  emulated netcards don't work with recent sunos kernel

Status in QEMU:
  New

Bug description:
  hi there,

i'm using qemu-kvm backend in version: # qemu-kvm -version
QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008 
Fabrice Bellard

and there are just *not working any of model=$type with combinations of recent 
sunos (solaris, openindiana, opensolaris, ..) ..

you can download for testing purposes iso from here: 
http://dlc-origin.openindiana.org/isos/147/ or from here: 
http://genunix.org/distributions/indiana/ << osol and oi are also bubuntu-like 
*live cds, so no need to bother with installing

behaviour is as follows:
e1000 - receiving doesn't work, transmitting works .. dladm (tool for handle 
ethers) shows that is all ok, correct mode is loaded up, it just seems like 
this driver works at 100% but ..

rtl8169|pcnet - works in 10Mbit mode with several other issues like high cpu 
utilization and so .. dladm is unable to recognize options for this kind of -nic

others - just don't work

.. i experienced this issue several times in past .. woraround was, that 
rtl8169 worked so-so .. with recent sunos kernel it doesn't.

it's easy to reproduce, this is why i'm not putting here more then launching 
script for my virtual machine:

# cat openindiana.sh
qemu-kvm -hda /home/kvm/openindiana/openindiana.img -m 2048 -localtime -cdrom 
/home/kvm/+images/oi-dev-147-x86.iso -boot d \
-vga std -vnc :9 -k en-us -monitor 
unix:/home/kvm/openindiana/instance,server,nowait \
-net nic,model=e1000,vlan=1 -net tap,ifname=oi0,script=no,vlan=1 &

sleep 2;
ip l set oi0 up;
ip a a 192.168.99.9/24 dev oi0;
