Subject: [PATCH] kvm: nVMX: Allow L1 to intercept software exceptions (#BP and #OF)
|
||||
Date: Wed, 14 Dec 2016 11:41:59 -0800
|
||||
|
||||
When L2 exits to L0 due to "exception or NMI", software exceptions
|
||||
(#BP and #OF) for which L1 has requested an intercept should be
|
||||
handled by L1 rather than L0. Previously, only hardware exceptions
|
||||
were forwarded to L1.

||||
