Thanks for the reply.
I had wrong understanding that Qemu runs in Guest.
But now I understand that *ioctl(fd, KVM_RUN, 0);* will tell KVM to
load the guest and whenever there is an exception in the guest, KVM
traps it and executes the host code post ioctl depending on the reason
for exit.
Can you point me to the code where the KVM traps the exception and
loads the host to execute the post ioctl code?
That's what vmx.c and svm.c in the kernel are about, look at
vmx_vcpu_run() and svm_vcpu_run().
