Clarification of ClearVM and ClearOS

Perhaps I'm just missing the obvious in the forums but I will risk a pair of stupid questions.

1) Is the ClearVM setup more similar to XenServer in that it installs a hypervisor only with extremely minimal Dom0 host base, or is it adding the KVM functionality and management tools to a standard ClearOS setup? Disk management and planning are required for either scenario, but the infographics don't really say anything technically useful.

2) Because management tools for Xen suck, I would like to migrate off of XenServer. I've been contemplating using a bare linux distro and loading up Xen on that or switching to KVM. Can ClearVM fairly easily migrate in a Xen vm and run it in KVM/ClearVM?
