this made me look into how cloud hypervisors actually work on HW level.. they all offload it to custom HW (smart nic, fpga, dpu, etc..). cpu does almost nothing except for tenant work. AWS -> Nitro, Azure -> FPGA, NVIDIA sells DPUs.

Here is interactive visual guide if anyone wants to explore - https://vectree.io/c/cloud-virtualization-hardware-nitro-cat...
