使用virt-manager启动Bliss OS虚拟机时出现PW context初始化失败错误求助

大家好，想请教个问题：我之前按照相关指南用QEMU运行Bliss OS一切正常，但现在尝试用virt-manager来启动配置好的虚拟机时，遇到了启动失败的问题，具体错误信息如下：

Error starting domain: internal error: process exited while connecting to monitor: 2024-08-25T13:58:29.563176Z qemu-system-x86_64: Failed to initialize PW context

对应的Traceback信息：

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 108, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn
    ret = fn(self, *args, **kwargs)
          ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/share/virt-manager/virtManager/object/dom...

有没有大佬遇到过类似的情况？或者能给我一些排查和解决的方向吗？非常感谢！
