Subject: Interrupt for HVM guests
Date: Fri, 05 Jun 2009 14:43:18 -0400	[thread overview]
Message-ID: <4A296746.3050204@ncsu.edu> (raw)
In-Reply-To: <C62EEA7B.AC3D%keir.fraser@eu.citrix.com>

I am trying to figure out how an HVM guest is passed an interrupt.  Say 
that a network packet has arrived and the QEMU driver in dom0 has to 
notify an HVM guest of the packet's arrival.  Could someone please give 
a brief, high-level description of this process?  I read the Intel 
Architectures Software Developer's Guide on VM Execution bits and 
Virtual interrupts and also some Xenwiki stuff about it but I'm still 
not sure what's going on.  I don't have any device pass-through or 
stubdom or PV Drivers for my HVM guest.  I would also appreciate 
references to some Xen files/functions related to this process.

Thanks,

John
