Based on comment #30, it sounds like the original problem of this bug
has been fixed, and since the remaining apic-related problem is tracked
in ticket #1395217 already, I think we can close this bug now (if you
don't agree, feel free to open this ticket again).

apparently it has something to do with x2apic. simply refining my cpu
line to be -cpu kvm64,-x2apic leads to a working network.

Stefan, thanks for your work.
I tested your patch in comment #29 and it does seem to solve the problem
for me for latest openindiana and also for latest nexenta core.
Also I checked vanilla rtl8139 and it seems to work for openindiana on
qemu-kvm-0.14.0 (with 0.13.0 I think I had problems).
Please test this patch:

QEMU loads checksum offload flags from every tx data descriptor. When a
multi-descriptor packet is sent, Solaris will only mark the first
descriptor with checksum offload flags.
I was able to reproduce this problem with qemu.git running OpenIndiana
148 with tap and bridge on the host. I did not see an issue with the
userspace network stack - seems to manifest itself as a checksum error
in transmitted packets.
Here is the host tcpdump during a TCP stall with mtu 1500:
Emulated NIC is e1000.
I found out that if one reduces the MTU on the client like ifconfig eth0 mtu
300 it seems ssh hangs much more rarely (but still hangs, at 300).
Reducing it on the virtualization host bridge is not enough though (unless you
are initiating ssh from the virtualization host
Hi all,
I can confirm this bug,
on latest openindiana-148 and qemu-kvm 0.13.0 you cannot even ping the
virtualization host.
With qemu-kvm-0.14.0 (just released!) you CAN ping the host: this is already an
improvement.
HOWEVER
biggest bug is still there: if you log in to the openindiana machine
I can confirm this. Just spent hours studying my network configuration in
OpenIndiana b148 running in Qemu KVM and figuring out what's wrong...
Everything's OK, network is up but I won't even ping the gateway.
Please fix this soon!

okay Stefan ..
thanks, i poked several people and trying to learn up how netstack works
.. i have no experience with programming drivers .. i hope that we'll
fix it soon cuz it's very bad that we're unable to use kvm|qemu

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I just tried a newer version of the indiana iso image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).
is this issue dead ?? can i do something for help to fix it?
regards, daniel

well, i did some more investigations and here come a results ..
this patch http://patchwork.ozlabs.org/patch/65137/raw/ solves problem
partially .. NICs are working with that but after a deeper look,
connection is lost when the netstack is flooded with higher traffic ..
i can connect with

well, this *fixed a issue .. it's very good that we (sunos guys) can now
use the best virt platform (kvm - IMO) ..
regards and thanks folks

Does the following qemu.git patch solve the problem?

Sorry about the partially mirrored mailing list thread. I expected

reproduced with latest vanilla qemu-kvm ..
i've just build it without any optimalizations like this: `./configure
--prefix=$HOME/chroot/opt/qemu-kvm-0.13rc1; make`
(qemu) info version
info version
0.12.91 (qemu-kvm-0.13.0-rc1)
it acts just same .. i'm trying at first to hunt down what has
added a output from `kstat -p e1000*` ..
call for more info if needed ..

ps. summary: everything seems fine (link statistics and so) but
receiving just doesn't work .. transmitting works
