vmm.h@ 76398

Last change on this file since 76398 was 76290, checked in by vboxsync, 6 years ago
VMM/HM: Nested VMX: bugref:9180 Added a new pre-init VMM call, invoked from HMR3Init() to copy VMX features to the VM structures earlier than HMR0InitVM does. This way the VMX features are available at the time of CPUMR3Init.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
