title: QEMU PCIe TLP Emulation
body: <p>Does QEMU emulate the PCIe Transaction Layer somehow?</p>
  <p>When I have a virtual Switch like (<a href="https://blogs.oracle.com/linux/post/a-study-of-the-linux-kernel-pci-subsystem-with-qemu" rel="nofollow noreferrer">https://blogs.oracle.com/linux/post/a-study-of-the-linux-kernel-pci-subsystem-with-qemu</a>) am I able to intercept at least the TLP's going over it? Or is the abstraction so high the the hypervisor does not go down to that layer at all.</p>
