xen-create-image 不会创建 inird 或 initramfs 映像，并且 domU 不会以系统映像启动

Question

我有 Fedora 19 作为 Dom0。要创建镜像，我运行

# xen-create-image --hostname=debian-wheezy --memory=512Mb --dhcp --size=20Gb --swap=512Mb --dir=/xen --arch=amd64 --dist=wheezy

生成完成后，我启动虚拟机并看到：

# xl create /etc/xen/debian-wheezy.cfg
Parsing config from /etc/xen/debian-wheezy.cfg
libxl: error: libxl_dom.c:409:libxl__build_pv: xc_dom_ramdisk_file failed: No such file or directory
libxl: error: libxl_create.c:919:domcreate_rebuild_done: cannot (re-)build domain: -3

在 /etc/xen/debian-wheezy.cfg 中我有

#
#  Kernel + memory size
#
kernel      = '/boot/vmlinuz-3.11.2-201.fc19.x86_64'
ramdisk     = '/boot/initrd.img-3.11.2-201.fc19.x86_64'

和ls -1 /boot/*201*表演

/boot/config-3.11.2-201.fc19.x86_64
/boot/initramfs-3.11.2-201.fc19.x86_64.img
/boot/System.map-3.11.2-201.fc19.x86_64
/boot/vmlinuz-3.11.2-201.fc19.x86_64

然后，如果我修复ramdisk.cfg 文件中的指令，/boot/initramfs-3.11.2-201.fc19.x86_64.img虚拟机将启动，但内部操作系统将无法启动。在 xl 控制台的末尾，我得到

dracut:/#

.img 文件/xen/domains/debian-wheezy存在并列在磁盘debian-wheezy.cfg 部分

所以我该怎么做？

更新：

我发现 xl 无法挂载图像。在 debian-wheezy.cfg 中，我有以下内容：

root        = '/dev/xvda2 ro'
disk        = [
                  'file:/xen/domains/debian-wheezy/disk.img,xvda2,w',
                  'file:/xen/domains/debian-wheeze/swap.img,xvda1,w',
              ]

并且 VM 中没有 /dev/xvda* 或 /dev/sda* 或 /dev/hda* 文件。

尝试使用它virt-manager来创建/管理您的虚拟机。
