Theoretically, you can run Xen for paravirtualization and kvm for full virtualization. Realistically, that's not trivial to accomplish: - Xen adds an additional addressing abstraction (machine addresses) that kvm has to be taught about - kvm uses privileged instructions which cannot be executed by a Xen guest (and would thus need assists) - VT returns to ring 0, and would need an assist to return to ring 1 where Linux (and kvm) lives - kvm wants to be pinned to a cpu while it's modifying VT state Another option is to use a small subset of kvm to run paravirtualized Xen guests on top of kvm (without Xen itself). -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- Using Tomcat but need to do more?
