hi,

I am seeing an unhandled vm exit: 0x11 on Win7 with KVM-88 release and
wondering if I am still able to dump the code from guest OS when this
happens. But it looks that all instructions are 0s after adding one
more print code after dumping the guest registers.

And it is very likely that this problem is fixed in the latest qemu
code base but I still would like to know how to debug and investigate
this kind of problem. BTW, I am using 32-bit qemu + 64-bit KVM kernel
module.

unhandled vm exit: 0x11
I happened to be in the intel docs today:
   0x11 (17) RSM. Guest software attempted to execute RSM in SMM.

As it happens, the 0x11 should be looked up as a KVM_EXIT_REASON (kvm.h), not in the manuals as I said. It's a kvm internal error.

What is RSM and SMM?

These are documented in the manuals.
