  • Sharing read-only data among virtual machines using coherent accelerator processor interface (CAPI) enabled flash
    Patent number: 10261703
    Abstract: Sharing read-only data among virtual machines (VM) using an attached coherent accelerator processor interface (CAPI) enabled flash storage (CeFS) is provided. The method includes mapping a file, by a virtual machine monitor, from the CeFS into a range of common memory in the virtual machine monitor. The VM shares the mapped file with at least one other VM at a range of common memory in their address spaces. A redirect-on-write filesystem (RoWFS) is created on the VM and the at least one other VM, whereby the RoWFS includes a read-only copy and a private copy of a linear memory map of the mapped file. A data page is read using the copy of the linear memory map, and the data page is modified using the private copy of the linear memory map.
