 * Ubuntu 後來取　KVM　捨 Xen，9.04　之後的 ubuntu kernel 都不支援 Xen dom0　Kernel (Ubuntu 的 OpenNEbula 和 Eucalyptus 套件都預設會使用 KVM)

 * Xen 官方的 2.6.18
 * 整合 Xen & lustre 的 2.6.22

There's a known problem with making ACPI modular.  Compiling them builting (=y) should work.

General setup ---> Choose SLAB allocator (SLUB (Unqueued Allocator)) ---> (X) SLAB

Processor type and features ---> Subarchitecture Type (PC-compatible) ---> (X) Enable Xen compatible kernel

Bus options (PCI etc.)  ---> [*] PCI support
