摘要
Systems and methods for managing message signaled interrupts in virtualized computer systems. An example method may comprise: intercepting, by a hypervisor running on a host computer system, a memory read operation initiated by a virtual machine with respect to a first interrupt mapping table, the first interrupt mapping table stored by a physical device associated with the virtual machine, the memory read operation specifying an offset relative to a base address of the first interrupt mapping table; reading at least part of the first interrupt mapping table; and returning, to the virtual machine, a value referenced by the offset within a second interrupt mapping table, the second interrupt mapping table residing in a memory of the host computer system.
