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 (‘interrupt’). -- Keir On 28/8/08 00:54, "Patrick F.

Specifically, is there a way to use interrupts in aiding the notification of arrived inter-domain messages to applications running on HVM guests? _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
