.. _virtio_user_for_container_networking:
* Cannot work with --no-huge option. Currently, DPDK uses anonymous mapping
under this option which cannot be reopened to share with vhost backend.
* Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8) hugepages.
- In another word, do not use 2MB hugepage so far.
+ If you have more regions (especially when 2MB hugepages are used), the option,
+ --single-file-segments, can help to reduce the number of shared files.
* Applications should not use file name like HUGEFILE_FMT ("%smap_%d"). That
will bring confusion when sharing hugepage files with backend by name.
* Root privilege is a must. DPDK resolves physical addresses of hugepages
