In one situation, where several domains have been created using overbooked
resources, would it be nice to have some resouce reclamation capability
which requires the cooperation between Xen and supported GuestOS?

I believe Xen has the similar primitives for requesting resources from
GuestOS side. And it seems reasonable and practical to add the reverse
functionality rescinding resource usage back from GuestOS. Such approach
may not be possible considering UML or VMWare, but with Xen, it should be
possible since modification on GuestOS can be made.
