Whether I have
REQUIREMENTS = "CLUSTER\"=xen\""
(the name of the cluster with one xen node)
or
REQUIREMENTS = "HYPERVISOR\"=xen\""
my VM's just stay forever in pending state.
Interestingly enough, if
I put REQUIREMENTS = "HYPERVISOR=\"kvm\""
then the VM does match and launch just fine.
Also, some other users who are trying to launch
jobs and not specifying any hypervisor or cluster are ending up
on the xen node by accident.
No idea from the scheduler log as to why it is not matching.

It turned out that a restart of oned was necessary and I did not
lose all the running VM's in the cloud.
Next question--if I have a working KVM OS image,
can I just install a kernel-xen in it, save it, and then
bring it up on the xen node?
If you are using HVM you do not have to change image (only xen
template). In case of PV you have to use kernel with domU support (of
course you need change also template).
Also is there any way by
using requirements field in the template to require the instance
to launch on Xen? (I have defined a second cluster "xen" with
the one node in it.)
In accordence with
http://opennebula.org/documentation:rel2.0:cluster_guide you can use:
REQUIREMENTS = "CLUSTER = \"xen\""
in your template file.
