FYI:
actually the vmware kernel leverages many open source drivers
from the linux kernel and I highly suspect that it is in fact
a custom linux kernel.
some evidence that supports this view is the recent
attempt of vmware to join the linux-distros mailinglist
to get early access to vulnerabilities in open source code.
you can just join this list if you offer a kind of "linux" distribution
(or something very close to it).
here is a thread for further reading on the case:
http://seclists.org/oss-sec/2014/q2/403
PS: regarding ovirt-node:
it's actually a very trimmed down linux system, just enough
to act as an hypervisor, so it's bare metal virtualization
(I would even argue that there is no such thing as a type 1
hypervisor, because if you talk about type 1 hypervisors
the hypervisor itself is the operating system kernel, which is also
the case for kvm, as it is a linux kernel module).

VMware says esxi is a bare-metal hypervisor and there is not an
underlying
os. Someone else says it is based on vmkernel operating system ( where
vmkernel is defined as a posix-like operating system).
In my opinion the oVirt node is to be intended something like ESXi: an os
with the smallest possible footprint, dedicated to run as a KVM hypervisor.
The difference being that it is based on Linux and not developed from
scratch.
