Hi,
I am seeing following build errors with latest vpp git repo. CPU on
the system I am building supports 'avx2'. Commenting 'avx2' in vnet.am
builds succesfully. However, I would like to use 'avx2' version of the
library. I have followed exact build instructions given in wiki.

VM I am using has 1GB memory and vpp fails to start with following
error message
May 25 23:07:12 rkerur: Main heap allocation failure!

Since 'main_heap_size' is defined to be 1GB (uword main_heap_size =
(1ULL << 30)), what is the minimum memory requirement for vpp
successful run?
Thanks.
