Subject: KVM_EXIT_HALT and KVM_CREATE_IRQCHIP
Date: Thu, 10 Jun 2010 12:52:24 +0300	[thread overview]
Message-ID: <4C10B5D8.2040409@cs.helsinki.fi> (raw)

Hi!

How is the guest supposed to halt the hypervisor if KVM_CREATE_IRQCHIP 
is being used? The kvm_emulate_halt() function seems to handle the halt 
event completely if irqchip_in_kernel() returns true and thus never 
exits to the hypervisor.

I see there's a KVM_GET_MP_STATE ioctl that can be used to check if 
state is KVM_MP_STATE_HALTED but as we never exit to the hypervisor, how 
is this supposed to work? Am I missing something obvious here?

			Pekka
