Hi,
I have a 82599ES that functions well on linux (i.e. ixgbe).
However, when binded to dpdk 100% of the received packets are counted as
missed (using testpmd as well as my own stable application), and non arrive
to the application.
I wonder what can be the reason. Why does it functions well on l
e
to count pkts in/out to and from the vm.
If someone has an idea how to do that i will be more than happy to hear.

i.e. on 1500 bytes packet size testpmd delivers ~9.82 gbps from port 1 to 2
and another ~9.82 gbps from port 2 to 1, while at the vm it only delivers
~3.9 gbps for each direction.

perf dropped
if using anonymous hugepages or macvtap。
1. Baseline: real hugepage + real pci pass-through
2. Anon hugepages vs hugepages
3. Real pci pass-through vs. macvtap

that forwarding ~5-6 gbps between two ports should be trivial, so
it will be great if someone can share its configuration for a tested setup.
Any further idea will be highly appreciated.
Thanks.

see significant difference
between the vm and the host which I can't fully explain.
any further idea?

Hi.
Some help is needed to understand performance issue on virtual machine.
Running testpmd over the host functions well (testpmd forwards 10g between
two 82599 ports).
However same application running on a virtual machine over same host
results with huge degradation in performance.
The testpmd th
install...).

Hi,
the silence confuses me, at least I would like to understand if it is well
supported or not for the release so I can decide whether to find an
alternative or not.
what is the trigger for the guest to send the VHOST_USER_SET_VRING_KICK?
Thanks

Hi,
I am following http://dpdk.org/doc/guides/sample_app_ug/vhost.html using
16.11 in order to have a simple VM forwarding packets from one NIC to
another efficiently, but it doesn't work... so I need some help to
understand what am i missing.
I am using x520 (intel 82599).
host is ubuntu 16.04 and
16 matches
