[Xen-devel] Interrupts in HVM inter-domain communication
What are the possible methods for inter-domain communication between HVM guests? Specifically, is there a way to use interrupts in aiding the notification of arrived inter-domain messages to applications running on HVM guests? -- Patrick F.

Yes, inter-domain event channels exist for this purpose. Basically a sticky bit in each domain, which the other can cause to be set. When a bit flips 0->1 that domain gets an async callback (interrupt¹). -- Keir On 28/8/08 00:54, "Patrick F.
