summary

ZVM implements CPU, memory, interrupt, I/O and timer virtualization on ARM64 and Zephyr, claiming an open‑source embedded real‑time hypervisor that runs Linux and Zephyr and uses vcpu threads, a master‑slave core0 host model, two‑stage (MMU) address translation and an mmio‑based mapping. Device support includes passthrough and fully virtualized devices with a virtual GIC. Tested on QEMU and ARM FVP and porting to RK3568, measured overheads are microsecond‑scale added latency in thread and interrupt paths.
