vMotion needs L2 adjacency to make live migrating VMs easy. Some software rely heavily on broadcast discovery messages and are thus designed for LAN usage not Internet connectivity but businesses try to stuff a square peg into a round hold.

I have a vHost which is sitting on a public IP in another country, while the rest of vSphere is here in RFC1918.

vMotion, Provisioning and backups work just fine.

vMotion doesn't need L2 at all, this is a flat out lie.
