[PATCH v3 0/4] nested vmx: enable VMCS shadowing feature
Changes from v2 to v3:
- Use pfn_to_paddr() to get the address from frame number instead of doing shift directly.
- Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields.
- Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled.
- Use clear_page() to set all 0 to the page instead of memset().
- Use domheap to allocate the

[PATCH 0/4] Add posted interrupt supporting
From: Yang Zhang <yang.z.zhang@Intel.com>
The follwoing patches are adding the Posted Interrupt supporting to Xen:
Posted Interrupt allows vAPIC interrupts to inject into guest directly
without any vmexit.
- When delivering a interrupt to guest, if target vcpu is running,
update Posted-interrupt requests bitmap and send a notification event
to the vcpu. Then the vcpu will handle this

[RFC PATCH v6 00/92] 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 VM-s
(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
