Question

我正在使用C＃和Xenserver API编写模拟XenCenter的WPF应用程序。我已从https://github.com/xenserver/xenadmin中删除了XenAPI解决方案并在我的应用程序中实现;我可以成功启动，停止，恢复和克隆虚拟机。不幸的是，我无法为所有VM拍摄快照。我正在使用两个VM来测试应用程序。 Windows XP SP3（未安装操作系统，仅安装VM）和Ubuntu 14.04 Trusty Tahr（操作系统已安装并正常运行）。当我调用快照功能时，它适用于Windows机器，但不适用于Ubuntu机器。两次尝试都在调试中提供类似的输出（如下）。我已经在https://github.com/xenserver/xenadmin/blob/master/XenModel/Actions/VM/VMSnapshotCreateAction.cs之后模拟了我的尝试。我会问Citrix问题是什么，但他们需要支付报酬而且我只是一名学生。有人可以帮忙吗？
