我有一台虚拟机（基于 Xen），我可以启动启动机器，但启动过程中出现一些警告。
正常吗？如果不正常，如何解决？

当我df -h启动后运行时，它是

答案1
空间耗尽永远不是“理想的”情况，解决方案就在消息本身中。
init：无法创建 pty - 禁用作业
init 的日志记录：临时进程生成错误：设备上没有剩余空间
因为该盒子可以启动、运行df并查找接近或达到 100% 利用率的磁盘。
答案2
如果是Ubuntu，那么可以全部忽略。
"init: Failed to create pty - disabling logging for job"
这是 Ubuntu 12.04 的一个已知错误
这个：
FATAL: Module nf_conntrack_ftp not found.
FATAL: Module nf_nat_ftp not found.
FATAL: Module nf_conntrack_netbios_ns not found.
我假设您正在使用自定义 Xen 自定义 domU 或类似的内核，要解决此问题，您可以删除 uwf，重新编译内核或调整 /etc/default/ufw 中的 IPT_MODULES。
希望这可以帮助。
