KVM虚拟机virt-manager打开控制台出错

In some circumstances, attempting to open the detail view of a VM produces the error:

'NoneType' object has no attribute 'change_run_text'

with the details:

Error launching details: 'NoneType' object has no attribute 'change_run_text'

Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 832, in _show_vm_helper

details.show()

File "/usr/share/virt-manager/virtManager/details.py", line 616, in show

self.refresh_vm_state()

File "/usr/share/virt-manager/virtManager/details.py", line 1285, in refresh_vm_state

self.change_run_text(vm.has_managed_save())

File "/usr/share/virt-manager/virtManager/details.py", line 1268, in change_run_text

self.widget("details-vm-menu").get_submenu().change_run_text(text)

AttributeError: 'NoneType' object has no attribute 'change_run_text'

virt-manager is at 1.4.0.

No steps to reproduce currently, but it very likely has something to do with saving the VM's state to disk.

The problem persists even after restarting virt-manager. Restarting libvirtd, however, resolves the problem.
