EOI virtualization is enabled if APICv virtual interrupt delivery is supported. Except for level triggered interrupts, the VM will not exit in case of EOI. In case of no APICv virtual interrupt delivery support, vLAPIC requires EOI from Guest OS whenever a vector was acknowledged and processed by guest. vLAPIC behavior is the same as HW LAPIC.

Section 29.1 discusses the virtual-APIC page and how the processor uses it to track the state of the virtual APIC. The following are the VM-execution controls relevant to APIC virtualization and virtual interrupts (see Section 24.6 for information about the locations of these controls): • …

Virtual-interrupt delivery has the same priority as that of VM exits due to the 1-setting of the “interrupt-window exiting” VM-execution control.1 Thus, non-maskable interrupts (NMIs) and higher priority events take priority over delivery of a virtual interrupt; delivery …

Hello, I'm having a hard time trying to find information related to timer interrupt delivery modes in ¨VMware. At the moment that a virtual machine should generate a virtual timer interrupt, it might not actually be running.

VMCS有对中断虚拟化和APIC的控制，这些控制都用起来以后，处理器会在non-root模式下模拟APIC的访问、跟踪Virtual APIC的状态、传递虚拟中断而不产生VM-Exit。 APIC V short for APIC Virtualization APIC V related controls: - Virtual-interrupt delivery - Use TPR shado

When that happens, does the currently executing instruction immediately serialize the OOO stream and jump to the vector like a typical interrupt delivery, or does VT-x's virtual interrupt delivery cause some other kind of resolution to take place?
