3 years ago It's suggested that DPVS run on physical server rather than VM. If you are using VM to test DPVS, make sure that your VM satisfies the following requirements.
- 2 cores at least, one for master, another for slave worker.
- 8GB memory,
- virtual nic supports flow director, configure one worker only if not.
In case of core dump, you could enable the DEBUG flag in src/Makefile and gdb it. Many more clues may be found then.
