Hi Mats,
Yes the virsh xml is created in essentially the same way. And the
setup in host is also the same as yours.
But no PCI passthru. As I understand, in a PF-VF deployment it makes
no sense for PCI passthru, coz the PCI device must be visible and
under control of host. (Pls correct me if Im wr

Hi Mats,
I didn't have any deviation. What I did is just loading ixgbe (with
extra params for vf, as you mentioned in your first email),
and DPDK is up and running in guest. Of course I also followed section
8.10 of the DPDK release notes.
I can switch between DPDK and ixgebvf in guest at runtime

Hi Qinglai,
How did you configure the PCI passthrough in KVM? Did you use command
line parameter as described in the instructions, or do you use virsh
XML files, or maybe using virt-manager?
The steps that works best (i.e. can receive but not transmit) are:
1) sudo modprobe ixgbe max_vfs=2
2) su
Hi Mats,
I've tried vf with 82599EB and it works fine. As long as the VF is
visible in guest, DPDK's VF driver should work just as ixgbevf, which
shares more or less the same code.
I don't understand why you would expect DPDK at guest to work as VF,
while the host has no ixgbe loaded.

Hi Qinglai,
Thanks for the response!
My previous attempt was with ixgbe loaded in the host. I also needed
to load ixgbevf, but this seems to be because of a short-coming in
libvirt. Maybe loading ixgbevf and then unbind it when running the
guest is what causes my problems. I could receive packets

This is my fourth mail in my desperate attempt to get DPDK running in
KVM and no comments so far, not even any "it works for me". Am I the
only one crazy enough to believe that this can be done?
Anyway, out of desperation I tried to get it running without having
ixgbe or ixgbevf kernel modules loa
Never mind, I was hit by the infamous MAC spoofing... I got it working
on both the host and the guest using ixgbevf driver, so apparently the
cables are correctly attached.
Using DPDK is still no-go. It can receive packets, but when sending
the packets the function returns success, but the driver
I have a follow-up on this:
ixgbe version 3.13.10-k
ixgbevf version 2.7.12-k
(These are what was provided by Ubuntu 13.10)
I tried the following sequence on the host, before starting the guest:
1) sudo rmmod ixgbe
2) sudo modprobe ixgbe max_vfs=2
3) sudo ifconfig em1 up # This is the physical f
I'm trying to get a modified version of the l2fwd example running, and
have problems with packets being silently thrown away. I can receive
packets, and my printf's indicates that the packets are being sent to
the correct port, using correct MAC address as source address. And
still, the packets are
