![XenServer 6.2 上的 Win2K P2V:VM 无法启动](https://linux22.com/image/647972/XenServer%206.2%20%E4%B8%8A%E7%9A%84%20Win2K%20P2V%EF%BC%9AVM%20%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8.png)
我正在尝试虚拟化(P2V)一个非常旧的 Win2K 服务器(IBM x345)及其相关存储:
主 C 盘,运行在由内部 ServeRAID HW 控制器和相关内部 HDD 提供服务的 RAID 5 逻辑阵列之上);
两个不同的附加 LUN(磁盘 S: 和 F:),通过连接到 SAN(其主阵列是 IBM DS-4300)的 QLA2XXX FC-HBA 提供服务。
我的目标是将所有这些迁移到由新的 Xen Server 6.2 平台提供服务的 VM 上。
为了避免源端的任何风险(顺便说一句:该系统或多或少是“关键的”,并且...重新安装它很容易成为一场噩梦,因为它上运行着非常旧的/遗留的/专有的/孤立的软件),我特意选择不是以任何方式更改原始操作系统(无 sysprep、无初步 xen-tools 安装、无任何新 sw 和/或配置)。
因此,我简单地执行了以下步骤:
- 在 XS 上定义一个具有适当 CPU 和内存的新 VM;
- 向这样的虚拟机添加三个不同且大小合适的磁盘;
- 使用 sysrescuecd 重新启动服务器和虚拟机;
- 通过 LAN 对三个源磁盘分别运行“dd”。
一旦“dd”完成:
- 我对虚拟机进行了快照;
- 我(尝试)启动虚拟机。
结果是(......毫不奇怪)这样的:
(顺便说一句:当虚拟机处于这样的环境中时,虚拟机的 CPU 一直处于 100% 的状态!)
因此,我通过使用 Live CD(sysrescuecd)或原始 Win2K 启动 VM 进行了一些健全性检查和修复。详情如下:
- 我可以成功访问三个磁盘上的所有数据,特别是 C: 磁盘;
- 我能够使用 Win2K“iso”启动虚拟机,然后从中启动通常修复文件和修复启动命令,来自恢复控制台;
- 我可以启动 Win2K 的新安装,并要求“修复”当前(并被安装程序正确找到/识别)的 Win2K 安装
- 我运行了 xenserver-linux-fixup-disk.iso(如果我理解正确的话,它应该有助于解决我所面临的问题......)。
上述任何测试(实际上重复多次)都会得到相同的结果:虚拟机甚至无法启动启动过程的早期阶段。
在最好的情况下,我已经成功获得了这一点:
因此操作系统(我猜是引导加载程序)似乎已找到,但……再次无法启动引导过程。同样在这种情况下,虚拟机的 CPU 停留在 100%。
由于启动过程似乎在很早的阶段就中断了(您会发现甚至连常见的基于文本的初始进度条都没有显示,在此期间可以按 F8 来选择高级启动参数/设置!)我确信解决方案应该很简单:可能是一个新的“引导加载程序”和/或一个新的“内核”能够访问 VM 的第一个 HD 上的 Win2K 安装。
最后说明一下:调查过程中,我发现磁盘几何结构不匹配。请注意下面的第 7-10 行:
root@sysresccd /root % sfdisk /dev/xvda
sfdisk: Checking that no-one is using this disk right now ...
sfdisk: OK
Disk /dev/xvda: 13054 cylinders, 255 heads, 63 sectors/track
Old situation:
sfdisk: Warning: The partition table looks like it was made
for C/H/S=*/254/63 (instead of 13054/255/63).
For this listing I'll assume that geometry.
Units: cylinders of 8193024 bytes, blocks of 1024 bytes, counting from 0

sfdisk: Input in the following format; absent fields get a default value.

Usually you only need to specify <start> and <size> (and perhaps <type>).
sfdisk: /dev/xvda1 :
testdisks 也证实了这种不匹配:

Current partition structure:

Bad sector count.

在完成所有这些之后,出现了一个(很容易预料到的)问题:有人可以帮我启动虚拟机吗?

答案1
我的建议:
安装 Windows 2000 VM。不需要与要迁移的版本完全相同。只需确保所有调整参数都正确即可。磁盘大小与源服务器类似(或略大)。
使用克隆兹拉执行磁盘映像备份和恢复,而不是简单的
dd
。Clonezilla 了解可能导致启动失败的 NTFS 变化。
