It does not depend on any lower-privileged OS kernel/code for its core functionality. This increases its security and can support a much smaller trusted computing base than a Type-2 hypervisor. Gunyah is an open source hypervisor. The source repo is available at https://github.com/quic/gunyah-hypervisor. The diagram below shows the architecture. :: Primary VM Secondary VMs +-----+ +-----+ | +-----+ +-----+ +-----+ | | | | | | | | | | | EL0 | APP | | APP | | | APP | | APP | | APP | | | | | | | | | | | | +-----+ +-----+ | +-----+ +-----+ +-----+ ---------------------|------------------------- +--------------+ | +----------------------+ | | | | | EL1 | Linux Kernel | | |Linux kernel/Other OS | ... | | | | | +--------------+ | +----------------------+ --------hvc/smc------|------hvc/smc------------ +----------------------------------------+ | | EL2 | Gunyah Hypervisor | | | +----------------------------------------+ Gunyah provides these following features. - Threads and Scheduling: The scheduler schedules virtual CPUs (VCPUs) on physical CPUs and enables time-sharing of the CPUs. - Memory Management: Gunyah tracks memory ownership and use of all memory under its control. Memory partitioning between VMs is a fundamental security feature. - Interrupt Virtualization: All interrupts are handled in the hypervisor and routed to the assigned VM. - Inter-VM Communication: There are several different mechanisms provided for communicating between VMs. - Device Virtualization: Para-virtualization of devices is supported using inter-VM communication. Low level system features and devices such as interrupt controllers are supported with emulation where required.
