Claim 12:
13. A computer-implemented method comprising:
creating, by a processor, a virtual swap space that is exposed to a host hypervisor software;
intercepting, by the processor, a first page selected by the host hypervisor software to be swapped out to the virtual swap space, wherein the first page is associated with first swap metadata;
mapping, by the processor, the virtual swap space to a physical swap space that is allocated to a type of page associated with the first swap metadata;
writing, by the processor, the first page to the physical swap space based on the first page having the first swap metadata; and
sending, to a destination host, a map from a virtual machine (VM) guest-physical page set to the physical swap space, wherein the VM guest-physical page set includes the first page and a non-swapped out page, wherein the destination host is notified that the first page is swapped out to the physical swap space, and wherein the first page is readable from the physical swap space by the destination host.
