ganeti 2.4-rc3安装在我的挤压服务器上进行得很好，我可以成功创build实例：
$ gnt-instance add -t plain -s 5G -o debootstrap+default -n obi-wan vm01 Wed Mar 2 17:12:51 2011 * disk 0, vg xenvg, name fdc7fa9e-19ac-405c-adad-f72da34d6682.disk0 Wed Mar 2 17:12:51 2011 * creating instance disks...

Wed Mar 2 17:13:03 2011 * starting instance... $ 它告诉我，实例运行正常：
$ gnt-instance list Instance Hypervisor OS Primary_node Status Memory vm01.physcip.uni-stuttgart.de xen-pvm debootstrap+default obi-wan.physcip.uni-stuttgart.de running 128M
但是debootstrap无法安装操作系统，因为无法安装根设备。 这是vm控制台的一个快照：
Begin: Loading essential drivers ... done. Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ...

Gave up waiting for root device.

Dropping to a shell!
什么安装：
ganeti集群信息：具有单个节点的集群（名为obi-wan）
gnt-cluster info Cluster name: vmcluster.physcip.uni-stuttgart.de Cluster UUID: 2ae3377c-8682-486d-9ac2-cdac43a136f7 Creation time: 2011-03-01 12:05:10 Modification time: 2011-03-02 14:12:48 Master node: obi-wan.physcip.uni-stuttgart.de Architecture (this node): 64bit (x86_64) Tags: (none) Default hypervisor: xen-pvm Enabled hypervisors: xen-pvm Hypervisor parameters: - xen-pvm: blockdev_prefix: sd bootloader_args: bootloader_path: initrd_path: /boot/initrd-2.6-xenU kernel_args: ro kernel_path: /boot/vmlinuz-2.6-xenU migration_mode: live migration_port: 8002 root_path: /dev/sda1 use_bootloader: False OS-specific hypervisor parameters: OS parameters: Hidden OSes: Blacklisted OSes: Cluster parameters: - candidate pool size: 10 - master netdev: xen-br0 - lvm volume group: xenvg - lvm reserved volumes: (none) - drbd usermode helper: /bin/true - file storage path: /srv/ganeti/file-storage - maintenance of node health: False - uid pool: - default instance allocator: - primary ip version: 4 - preallocation wipe disks: False Default node parameters: oob_program: None Default instance parameters: - default: auto_balance: True memory: 128 vcpus: 1 Default nic parameters: - default: link: xen-br0 mode: bridged
为xen-pvm设置的默认root_path只是错误的。 我通过改变了id
gnt-cluster modify --hypervisor-parameter xen-pvm:root_path='/dev/xvda1'
和debootstrap安装挤压就好了！
这是我的实例创build代码：
-H xen-pvm:kernel_path=/boot/vmlinuz-2.6-xenU,initrd_path=/boot/initrd-2.6-xenU,blockdev_prefix=xvd,root_path=/dev/xvda1
