[Xen-devel] [PATCH v3 0/4] Nested VMX: APIC-v related bug fixing

[Yang Zhang <yang.z.zhang@xxxxxxxxx>]

From: Yang Zhang <yang.z.zhang@xxxxxxxxx>

The following patches fix the issue that fail to boot L2 guest on APIC-v
available machine. The main problem is that with APIC-v, virtual interrupt 
inject
L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is 
running,
L1 will detect interrupt through vmexit with reason external interrupt. If this 
happens,
we should update RVI/SVI to make APIC-v working accordingly.

Changes from V2:
*   Rebase on top of Xen upstream
*   Merge patch 1(Introduce interrupt source supporting) and patch 3(Add 
interface to update vPPR)
    into the place where there were used.
*   Reorder the patch set.

Yang Zhang (4):
  Nested VMX: Check whether interrupt is blocked by TPR
  Nested VMX: Force check ISR when L2 is running
  Nested VMX: Clear APIC-v control bit in vmcs02
  Nested VMX: Update APIC-v(RVI/SVI) when vmexit to L1
