Does that mean KVM has no vSwap?
KVM, OpenVZ, Xen, VMWare, dedicated servers have swap too, even your notebook and desktop pc have swap. Both on Linux and Windows. But on Windows its not a separate partition, its just a file called PageFile. You can enable or disable it on all kind of operating system. Its basically acts like as your RAM, but it uses our HDD or SSD, so its much slower.
Oh...so it is a slow RAM 'like' thing...
It's not like RAM. It temporarily stores the info from the RAM into your HDD to free up RAM. (Things that go to SWAP are stuff that isn't accessed)
KVM, Xen, dedicated servers, or any hardware based virtualization can have SWAP. They can also disable SWAP if they don't want it.
