Hi,

one more VTi question:
nested_dtlb_miss is defined as:
ENTRY(vmx_nested_dtlb_miss)
    VMX_DBG_FAULT(5)
    VMX_FAULT(5)
END(vmx_nested_dtlb_miss)

that is a nested dtlb miss is reflected to the domain.
That also means that IO accesses are *not* allowed when vpsr.ic = 0.  Right ?
That also means that this fault can be reflected when the vcpu is in
(meta)physical mode, doesn't it ?

Tristan.
