After 18.05, more hugepage pages can be represented by single fd （file descriptor）file, so virtio-user can work with 2M hugepage now. The key parameter is "--single-file-segments" when launch virtio-user. + +Test Case1: Basic test for virtio-user 2M hugepage +=================================================== + +1.
