An DPDK error about "Cannot create lock on 'var/run/dpdk/rte/config'. "

I tried to run two applications on one server, when I run the second application, the following error will be reported:

Cannot create lock on 'var/run/dpdk/rte/config'.

How should I solve this problem so that I can run multiple DPDK programs at the same time?

Solution

  • That's done with the EAL parameter --file-prefix.

    You'd run one program with --file-prefix <prefix 1> and the second one with --file-prefix <prefix 2> (any unique names will do). Since it's an EAL parameter, make sure that it gets passed to the program before the -- parameter separator.
