我有一台 Windows Server，其中板载 SATA 控制器坏了，机器无法识别任何连接的磁盘。

为了克服这个问题，我正在考虑购买 PCI-E SATA 控制器并在其上连接所有可用的磁盘设备。

这个控制器是否等同于板控制器。简而言之，我能否从连接在 PCI-E 控制器上的磁盘毫无问题地引导我的机器？我是否需要重新安装操作系统（Windows Server）或者它会按原样工作？

为了避免混淆，我所说的机器不是机架式服务器或刀片服务器，而是或多或少用作服务器的高端“桌面”机器。

更新 19.06.2015

我刚刚安装了 PCI-E SATA 控制器，一切运行顺利，无需额外配置重新安装。

任何启动 nova 计算服务的尝试都失败并出现错误HypervisorUnavailable: Connection to the hypervisor is broken on host:

没有其他日志文件指示任何错误 syslog，dmesg也 /var/log/libvirt/libvirtd.log没有显示任何问题

libvirt 配置 ( /etc/libvirt/libvirtd.conf) 设置为记录错误 log_outputs="3:syslog:libvirtd"

在出现错误之前，节点运行平稳，没有进行任何更改。
