Won't work on Azure #106

Open shemminger opened 5 years ago

shemminger commented 5 years ago

There a couple of problems that keep dpdk-ans form working on Azure.

First the current CPU on bigger machine types is reported as core-avx2 by install-deps.sh. Even if I just link in the haswell binaries, it still doesn't start because.

Second, the network interface on Azure is using failsafe PMD and MLX as a hidden device. Even if you get the portmask right, it fails when I start it as:

ans -w a8f0:00:02.0 -l 4,5 -n 4 -- -p 0xf --config='(1,4,5)'

USER1: rte_ip_frag_table_create: allocated 25165952 bytes at socket 0 add veth1 device, kni id 0 USER8: LCORE[4] Interface veth1 if_capabilities: 0x800e USER8: LCORE[4] Interface (veth1) isnt' added

Of course since this is all in your non open source code :-( No outside party can fix it.

Please share your all startup log.

You may try below command. ans -w a8f0:00:02.0 -l 4,5 -n 4 -- -p 0x1 --config="(0,0,5)".
