Xen 运行后无法启动

  • 772

我一直在用一个 dom0 和 3 个 domU 设置这个 Debian Stable 系统。它运行了好几天，我几乎准备好将它部署到机架上。但是昨晚我第一次关闭了所有三个domU仍然在运行，今天我启动它时，xend无法启动。在 /var/log/messages 中，我有：

Apr 18 13:01:33 xen-test BLKTAPCTRL[4248]: blktapctrl: v1.0.0

Apr 18 13:01:33 xen-test BLKTAPCTRL[4248]: Unable to start blktapctrl

在 /var/log/xen/xend.log 中，我有这个：

关于可能出了什么问题的任何线索？

    好的，rm -rf /var/lib/xend/*解决了问题。但我仍然想知道为什么以及它是否可能会回来。

    ....时间流逝....

    现在我发现我的 /var/lib 分区太小了，而且它被填满了。快速 lvcreate、mkfs.ext3 并复制一些文件并编辑 /etc/fstab，我可以开始了。
