Xen 工作后无法启动

我一直在设置这个 Debian Stable 系统，其中包含一个 dom0 和 3 个 domU。几天来它运行良好，我几乎准备好将它部署到机架上。但昨晚我第一次关闭了它，所有三个 domU 仍在运行，今天当我启动它时，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 中有以下内容：

有任何线索表明可能出了什么问题吗？

答案1

好的，rm -rf /var/lib/xend/*问题解决了。但我仍然想知道原因以及它是否可能再次出现。

....时间流逝....

现在我发现我的 /var/lib 分区太小了，它快要满了。快速创建 lvcreate、mkfs.ext3 并复制一些文件，然后编辑 /etc/fstab，就可以了。
