 * 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)
----
= 【1.dom0 Kernel version】 = 
 * Xen 官方的 2.6.18
 * 整合 Xen & lustre 的 2.6.22
 * Xen 官方的 2.6.27
{{{

#!sh
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
                             [*]   Xen PCI Frontend

Change <M> 802.1d Ethernet Bridging to <*> 802.1d Ethernet Bridging:

Networking support ---> Networking options ---> <*> 802.1d Ethernet Bridging

Disable 10000 Mbit Ethernet (otherwise the build process will most likely fail):

Device Drivers ---> [*] Network device support ---> [ ] Ethernet (10000 Mbit) --->

Make the Xen section look as follows (make sure you select Xen version compatibility (3.0.4 and later) instead of Xen version compatibility (3.0.2 and later)):
