[PATCH v2 0/3] nested vmx bug fixes
Changes from v1 to v2:
- Use a macro to replace the hardcode in patch 1/3.
This patchset fixes issues about IA32_VMX_MISC MSR emulation, VMCS guest area
synchronization about PAGE_FAULT_ERROR_CODE_MASK/PAGE_FAULT_ERROR_CODE_MATCH,
and CR0/CR4 emulation.
Please help to review and pull.
Thanks,

[RFC PATCH v7 00/78] VM introspection
The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place
