Yes. It's more like VMware ESX server: rather than having a 'hostOS' there's a custom VMM. > -- if yes, is it reasonable to expect that a patched (customized for a > laptop) kernel that includes swsusp2 and encryption (among other > things) will be able to support Xen? Given that the host is a custom VMM rather than linux, this question doesn't make sense. You can suspend/migrate guest OSes, but not the host VMM itself. As regards encryption, you can compile it into the guests. There's also some support for network encryption in the Xen 1.3vnet tree. This will be rather more complete in the new IO model in 1.4. > -- is Xen at all suitable for the following usage scenario: a laptop > host, with frequently changing networking, software suspend (via > swsusp2), Xenolinux without real-world networking > (e.g. host<->Xenolinux communication only)? Xen is (currently) more targeted at clusters of servers rather than laptops. However, I do have Xen installed on my Toshiba R100.
