In CoCo environments there can be more than one hypervisor beneath the
guest. For example KVM as the untrusted host, SVSM or another para-visor
as the trusted in-guest hypervisor. On TDX there is also the TDX module
in-between, which is another level of hypervisors. ARM and Risc-V will
have similar architectures.
