创建虚拟机时，使用admin_pass metadata为administrator账户设置初始密码。在启动虚拟机时，报如下错误：
[-]
Using admin_pass metadata user password. Consider changing it
as soon
as possible
[-] plugin
'SetUserPasswordPlugin' failed
with error
'Set user password failed: ????????????????????????????????????'
[-]
Set user password failed: ????????????????????????????????????
由于编码的问题看不到错误内容，后来才知道，设置的初始密码太简单，不符合windows server的密码要求。
更新admin_pass metadata，设置复杂的满足要求的密码，重建虚机，查看日志，正常启动。
