It relies on your hypervisor and/or network hardware to provide that. In an ideal circumstance (e.g. running on a multiqueue NIC with VFIO or virtio acceleration), your VM can talk directly to the network hardware. Major clouds will provide something morally equivalent via their newer network interfaces (gVNIC etc.).
