Subject: KVM guest interrupts, traps, and, exceptions
Date: Sat, 27 Mar 2010 17:43:55 +0200 [thread overview]
Message-ID: <4BAE27BB.8040000@cs.helsinki.fi> (raw)
Hi Avi,
I'm continuing my journey through the KVM API documentation and I'm now
scratching my head on how interrupts, traps, and exceptions are
supported by the API. I see KVM_CREATE_IRQCHIP and KVM_IRQ_LINE but I'm
unable to work out how the host is notified of such events. For example,
if the guest does
int $0x10
is there some KVM_EXIT "exit reason" like we have for IO? Is there some
other mechanism for that? As I haven't yet set up anything related to
IRQs I can see the host just deadlock on user interrupts.
Pekka
