Hi. When I try to boot a Windows 10 ISO, i get this error:

Error starting an installation:constructor returned NULL

Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/create.py", line 1999, in _finish_clicked self._start_install(self._guest) File "/usr/share/virt-manager/virtManager/create.py", line 2092, in _start_install progWin.run() File "/usr/share/virt-manager/virtManager/asyncjob.py", line 284, in run Gdk.Cursor.new_from_name(gdk_window.get_display(), "progress")) TypeError: constructor returned NULL

Reinstalled kvm-host and kvm-extras but this problem persists.

I can confirm this - I thought it was a kvm kernel module problem but it is probably something else. Intel folks - are there changelogs we can look at if we want to try troubleshooting this ourselves?

Oo there might not be. @gtkramer @phmccarty thoughts on getting release notes published on the website. Would you prefer release notes on the mailing list? Since we try to release twice a day it seems like it might be just noise a lot of folks would rather avoid. Perhaps a separate mailing list though.

Hello, This is a duplicate of #782

As stated in a comment there, we'll have virt-manager downgraded while I get the new version to work out of the box.

are there changelogs we can look at if we want to try troubleshooting this ourselves?

@znmeb Please consider opening a new issue with this request, so it's not lost once I close this report.

@znmeb @mariojuniorjp release 29590 (or later) should have virt-manager back to a working state.

thanks for your bug report 🎉
