版本 centos pass random manager output seed use arch
報錯信息：
[root@monitor log]# virt-sysprep -d centos6-raw40 [ 0.0] Examining the guest ... virt-sysprep: error: libguestfs error: qemu-img: /tmp/libguestfs6olf8r/overlay1: qemu-img exited with error status 1. To see full error messages you may need to enable debugging.

因為virt-sysprep命令是libguestfs-tools工具下命令的一個，所以先查看了libguestfs-tools的版本：
[root@monitor qemu]# rpm -qa|grep libguestfs-tools libguestfs-tools-1.28.1-1.55.el7.centos.4.noarch libguestfs-tools-c-1.28.1-1.55.el7.centos.4.x86_64
發現版本是libguestfs-tools-1.28.1-1.55。而另外一臺執行virt-sysprep -d可以成功的。所以看一下另外一臺的libguestfs-tools版本：
[root@zabbix ~]# virt-sysprep -V virt-sysprep 1.36.3rhel=7,release=6.el7_4.3,libvirt [root@zabbix ~]# rpm -qa|grep libguestfs-tools libguestfs-tools-1.36.3-6.el7_4.3.noarch libguestfs-tools-c-1.36.3-6.el7_4.3.x86_64
發現版本是libguestfs-tools-1.36.3，於是就升級libguestfs-tools。
[root@monitor qemu]# yum upgrade libguestfs-tools
此時發現版本為：libguestfs-tools-1.36.3
[root@monitor qemu]# virt-sysprep -V virt-sysprep 1.36.3rhel=7,release=6.el7_4.3,libvirt
最後清理信息成功：
