12 Gunyah is a Type-1 hypervisor which is independent of any OS kernel, and runs in
15 security and can support a much smaller trusted computing base than a Type-2
16 hypervisor.
18 Gunyah is an open source hypervisor. The source repository is available at

5 Message queue is a simple low-capacity IPC channel between two virtual machines.
7 message queue is unidirectional and buffered in the hypervisor. A full-duplex

32 queue is being used to implement an RPC-like interface.

40 4. Gunyah raises the corresponding interrupt for VM_A (Tx vIRQ) when the message
