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 |
