嘗試在 Xen 上創建 ElementaryOS PV 來賓

我正在嘗試將 ElementaryOS 作為 pv 來賓安裝在我的伺服器上以進行測試。

Elementary OS 是 Ubuntu Precise 的一個分支。Elementary 不支持 PV，但是，我可以從以下位置獲取相應的 ubuntu 圖像：

$$ mirror $$/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/initrd.gz $$ mirror $$/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/vmlinuz

這是我的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'

到目前為止它正在工作，但我剛剛收到以下我擔心的錯誤。有人會查看我的 cfg 並確保我的所有設置都正確嗎？

當然，我可以將elementaryOS 安裝為HVM 來賓，但這更具挑戰性。

感謝您的幫助和建議

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，我已將 filename.cfg xvda1 更改為 xvda（參見範例）：

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