--- Comment #4 from masahiro nemoto (masahiro.nemoto.es@s1.ntt-tx.co.jp) ---
Hello Vipin,

Apologize about my late reply.

First of all, we have tried '--base-virtaddr and --single-file-segments' option
when starting primary process using DPDK20.02, ASLR enabled.

1. Result with DPDK20.02
Segmentation fault was observed when two secondary process(spp_vf) try to use
vhost.

2. Result with DPDK20.05
Segmentaion fault was NOT observed with the same condition above.

3. Analysis
Vhost related bug is fixed and merged from DPDK20.05 and this maybe the cause
difference of results.
(commit 7470f845c17ac27ce08b22f3c024169e51ade990)

4. Document impact
- Document for SPP 20.02, ASLR disable can NOT be deleted.
- Document for SPP 20.05 or onward, ASLR disable can be deleted(but should be
tested carefully)

What do you think?
