ZVM: Zephyr-based Virtual Machine
summary
ZVM implements an ARM64 Zephyr host that runs Linux and Zephyr guests and provides CPU, memory, interrupt, I/O and timer virtualization; vCPUs are implemented as threads with a vcpu-as-thread Master/Slave core model and IPIs for signaling. Memory uses two-stage address translation with an mmio-based mapping and VM-domain/partition/block structures. Devices support both pass-through devices and fully virtualized MMIO with a virtual GIC for injected interrupts. Tested on QEMU and ARM FVP, guest boot succeeds and latency increases stay within microseconds for thread creation, switching and interrupt response.
