尝试在 Xen 上创建 ElementaryOS PV 客户机

为了测试目的，我尝试在我的服务器上安装 ElementaryOS 作为 pv guest。

Elementary OS 是 Ubuntu Precise 的一个分支。Elementary 不提供 PV 支持，但是我可以从以下位置获取相应的 ubuntu 映像：

[镜像]/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/initrd.gz [镜像]/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/vmlinuz

这是我的 elementaryOS.cfg 的副本

name = "elementary"
kernel = "/home/curios/elementary/vmlinuz"
ramdisk = "/home/curios/elementary/initrd.gz"
memory = "1024"
disk = [ "phy:/dev/vg0/elementary,sda1,w", "file:/home/curios/elementary/elementaryos-stable-amd64.20130810.iso,sdb,r" ]
vif = ['bridge=xenbr0']
on_reboot = 'destroy'
on_poweroff = 'destroy'

到目前为止一切正常，但我刚刚收到以下令我担心的错误。有人能帮我检查一下我的 cfg 并确保我已正确设置所有设置吗？

当然，我可以将 elementaryOS 安装为 HVM 客户机，但这更具挑战性。

谢谢你的帮助和建议

Looks like you're mapping the LV as xvda1. Don't do that if you're
using OS installer. Map it as xvda instead.

You should only map block devices as (xv/s/h)da1 if you're using tools
like debootstrap/yum or doing manual copy from an existing system.

Also if you want to use ext4 as "/", don't forget to have a separate
/boot with ext3 since like Mark said, by default Centos' pygrub
doesn't support ext4.

就我而言，我在 filename.cfg 中将 xvda1 更改为 xvda（参见示例）：

disk        = [
                  'phy:/dev/vgxen/calculus-root,xvda,w'
              ]
