HOST VIRTUAL ADDRESS RESERVATION FOR GUEST MEMORY HOT-PLUGGING

摘要

An example method for host virtual address reservation comprises: reserving a host virtual address range within a virtual address space of a computer system; associating a first virtual memory device with a first guest physical address range a virtual machine running on the computer system; associating a second virtual memory device with a second guest physical address range of the virtual machine; mapping a first guest physical address of the first guest physical address range to a first host virtual address of the host virtual address range, wherein the first host virtual address is identified by an offset with respect to the first guest physical address; mapping a second guest physical address of the second guest physical address range to a second host virtual address of the host virtual address range, wherein the second host virtual address is identified by the offset with respect to the second guest physical address.

1. A method, comprising:
reserving, by a processing device of a host computer system, a host virtual address range within a virtual address space of the host computer system; associating a first virtual memory device with a first guest physical address range of a physical address space of a virtual machine running on the host computer system; associating a second virtual memory device with a second guest physical address range of the physical address space of the virtual machine; and mapping a first guest physical address of the first guest physical address range to a first host virtual address of the host virtual address range, wherein the first host virtual address is identified by an offset with respect to the first guest physical address; and mapping a second guest physical address of the second guest physical address range to a second host virtual address of the host virtual address range, wherein the second host virtual address is identified by the offset with respect to the second guest physical address.
