VMX definitely does not (IIUC). I don't know enough about SVN to say for sure, but my gut tells me that its not likely. A physical CPU can only accept a single vector at a time, so I bet the virtual ones do as well. If there is more than one pending, I think the intention is to both inject the virq and set the IRQ_WINDOW_EXIT feature to exit on the next RFLAGS.IF window.
