Hello Vipin,

Apologize about my late reply.

First of all, we have tried '--base-virtaddr and --single-file-segments' op=
tion
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 u=
se
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 cau=
se
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?
