[dpdk-dev] warning on remapping memory

[Yongseok Koh <yskoh@mellanox.com>]

Hi Anatoly,

There's a report that remap fails on a specific x86 host.
We can silence this warning by specifying '--base-virtaddr',
but wondering if you know in which case it could happen.

Log attached.


Thanks,
Yongseok
