什么意思？我运行的内核版本 3.1.5 已经包含了对XEN的支持了：
已经发过 /boot/config-3.1.0-1-amd64的XEN编译配置信息， 这里是内核信息： # apt-cache show linux-image-3.1.0-1-amd64 ... Package: linux-image-3.1.0-1-amd64 Status: install ok installed Priority: optional Section: kernel Installed-Size: 101630 Maintainer: Debian Kernel Team <debian-ker...@lists.debian.org> Architecture: amd64 Source: linux-2.6 Version: 3.1.5-1 Provides: linux-image, linux-modules-3.1.0-1-amd64 Depends: module-init-tools, linux-base (>= 3~), initramfs-tools (>= 0.99~) | linux-initramfs-tool Pre-Depends: debconf | debconf-2.0 Recommends: firmware-linux-free (>= 3~) Suggests: linux-doc-3.1, grub-pc | extlinux | lilo (>= 22.8-8.2~) Breaks: initramfs-tools (<< 0.99~), lilo (<< 22.8-8.2~) Description: Linux 3.1 for 64-bit PCs The Linux kernel 3.1 and modules for use on PCs with AMD64 or Intel 64 processors. . This kernel also runs on a Xen hypervisor. It supports both privileged (dom0) and unprivileged (domU) operation. 也是确认包含XEN的支持的，但是却不能执行xen的工具： root@vc:~# xl ERROR: Can't find hypervisor information in sysfs! root@vc:~# xm ERROR: Can't find hypervisor information in sysfs! 查看这些脚本后发现是因为目录 /sys/hypervisor 为空才出错的。
