Hi All,
We have VMs on a physical server with both VMs having 1 core 7 GB RAM
with DPDK 16.04. The VMs are communicating using SR-IOV (per VM 1 VF
is assigned). We thought of running the test_pmd_perf to test the
number of cycles taken for RX/TX. But we are unable to get it working.
Even if we assign 4 VCPUs to the VM the app says "*no avail lcore to
test*." The command we are using are:
As far as I trail its origin in source, alloc_lcore() errors out in a
situation when you do not have those lcores mentioned in -c or -l to app
which are from socket where your ports are actually attached. You can
print out target socket through te_eth_dev_socket_id(port_id).
You need to pass one lcore atleast from this socket, instead of socket 0
(which is case by default for lcores 0xf).
Use lscpu and find out what lcores you can pass from target socket id.

cd dpdk16.04/app/test
./build/app/test -c f -- -p 1
RTE>> pmd_perf_autotest
On searching we found that it might be an issue with our VMs using SRIOV.
Please guide us on this.
Thanks,
Priyanka
