[править] Introducing xenner
- Gerd Hoffman
- Red Hat
xenner is a utility which is able to boot xen paravirtualized kernels, without the xen hypervisor, using kvm instead.
xenner runs the xen guest kernel and a small xen emulator together as kvm guest. The emulator does the bare minimum needed to make the guest kernel happy. As we run in a vmx container anyway we don't bother checking anything unless absolutely needed. We also don't try to protect the emulator memory against the kernel.
xenner itself obviously can't trust the guest and must check things carefully. It isn't very good at that yet due to still being at proof-of-concept state. Right now guests can trivialy segfault and exploit xenner.
