當​​​​​​​您​​​​​​​欲​​​​​​​開​​​​​​​啟​​​​​​​ xend 服​​​​​​​務​​​​​​​時​​​​​​​沒​​​​​​​有​​​​​​​反​​​​​​​應​​​​​​​。​​​​​​​您​​​​​​​可​​​​​​​以​​​​​​​輸​​​​​​​入​​​​​​​ xm list1 並​​​​​​​接​​​​​​​收​​​​​​​下​​​​​​​列​​​​​​​： 
Error: Error connecting to xend: Connection refused. Is xend running?
您​​​​​​​嘗​​​​​​​試​​​​​​​手​​​​​​​動​​​​​​​執​​​​​​​行​​​​​​​ xend start 但​​​​​​​有​​​​​​​更​​​​​​​多​​​​​​​錯​​​​​​​誤​​​​​​​出​​​​​​​現​​​​​​​: 
Error: Could not obtain handle on privileged command interfaces (2 = No such file or directory)
Traceback (most recent call last:)

這​​​​​​​種​​​​​​​情​​​​​​​況​​​​​​​通​​​​​​​常​​​​​​​發​​​​​​​生​​​​​​​於​​​​​​​當​​​​​​​您​​​​​​​充​​​​​​​新​​​​​​​啟​​​​​​​動​​​​​​​您​​​​​​​的​​​​​​​主​​​​​​​機​​​​​​​至​​​​​​​一​​​​​​​個​​​​​​​非​​​​​​​ xen-hypervisor 核​​​​​​​心​​​​​​​的​​​​​​​核​​​​​​​心​​​​​​​。​​​​​​​欲​​​​​​​修​​​​​​​改​​​​​​​這​​​​​​​個​​​​​​​問​​​​​​​題​​​​​​​，您​​​​​​​必​​​​​​​須​​​​​​​在​​​​​​​開​​​​​​​機​​​​​​​時​​​​​​​（或​​​​​​​將​​​​​​​ xen-hypervisor 核​​​​​​​心​​​​​​​預​​​​​​​設​​​​​​​於​​​​​​​您​​​​​​​的​​​​​​​ grub.conf 檔​​​​​​​案​​​​​​​中​​​​​​​）選​​​​​​​取​​​​​​​ xen-hypervisor 核​​​​​​​心​​​​​​​。​​​​​​​
