Hi,
I cannot invoke virtio-net PMD at least on Ubuntu12 and Ubuntu14 QEMU guest.
This behavior might be seen on other users environment also, so I report it.
.
Here is error log.
$ ./testpmd -c f -n 1 -- -i
....snip....
Configuring Port0 (socket0)
Fail to configuring port 0 tx queues.
EAL: Error - exiting with code: 1
Cause: Start ports failed
$
As a result of bisect, it seems this behavior is caused by following patch.
61b16f0f167a331e65f0729b3554ded0440b545b
virtio: check for transmit checksum config error
After revert the patch, I haven't seen the error.
My question is that after applying this patch, should I specify some
specific parameters for QEMU virtio-net device?
Here is my parameters of virtio-net.
-device
virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:c6:a7:44,bus=pci.0,addr=0x5
\
-netdev tap,id=hostnet1
Also could someone reproduce the same issue?
My host is ubuntu14, and I am using QEMU I've got using apt-get.
Thanks,
Tetsuya
