Zusammenfassung:Communicating a low-latency event across a virtual machine boundary. Based on an event signaling request by a first process running at a first virtual machine, the first virtual machine updates a shared register that is accessible by a second virtual machine. Updating the shared register includes updating a signal stored in the shared register. The first virtual machine sends an event signal message, which includes a register identifier, through a virtualization fabric to the second virtual machine. The second virtual machine receives the event signaling message and identifies the register identifier from the message. Based on the register identifier, the second virtual machine reads the shared register, identifying a value of the signal stored in the shared register. Based at least on the value of the signal comprising a first value, the second virtual machine signals a second process running at the second virtual machine.
