The guest runs in a separate virtual address space enforced by the CPU hardware. A bug in the guest kernel cannot access host memory because the hardware prevents it. The host kernel only sees the user-space process. The attack surface is the hypervisor and the Virtual Machine Monitor, both of which are orders of magnitude smaller than the full kernel surface that containers share.
The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.
