| description | A method, system and computer program product for providing a guest with access to a virtual storage on a physical storage using a peripheral component interface hub. In one embodiment, the method comprises the guest sending to the peripheral component interface hub a request to access the physical storage, the request including physical addresses of the physical storage, and the peripheral component interface hub sending specified information about the request to a hypervisor. This method further comprises the hypervisor determining whether to grant or to reject the request; and when the hypervisor grants the request, the hypervisor sending a configuration command to the peripheral component interface hub. This command includes a mapping of addresses from the physical storage to addresses from the virtual storage. In an embodiment, the peripheral component interface hub uses this mapping to replace the addresses in the request with translated virtual addresses. |
