same problem here.
running

also reveals:

Seems to be some version mismatch ...

Same problem for me

I'm seeing this too. The exact same traceback as the OP, triggered when trying to open the dialog for either QEMU or LXC.

Same problem.
I tried to restart libvirt, ``sudo systemctl restart libvirtd.service``.
When I typed ``sudo systemctl status libvirtd.service``, it printed out
...
Could not find 'ebtables' executable
Cannot find 'pm-is-supported' in path: No such file or directory
...
So I installed ``ebtables`` and ``pm-utils`` and restarted ``libvirtd.service``.
``libvirtd.service`` can restart normally, but ``virt-manager`` still gets ``'NoneType' object has no attribute '__getitem__'``.

approved.

I'm not able to see or start my existing VMs.

Same problem here. I tought is related to a python update I made yesterday

As a work around to start ones virtual machines:

$ virsh -c qemu:///system start NAME_OF_VM

and then connect via VNC as usual

Same problem here. System update failed initially due to a new dependency, libvirt-python-1.2.0-1, with the message:

error: failed to commit transaction (conflicting files)
libvirt-python: /usr/lib/python2.7/site-packages/libvirt.pyc exists in filesystem
Errors occurred, no packages were upgraded.

Removing /usr/lib/python2.7/site-packages/libvirt.pyc allowed the update to be applied, but virt-manager fails to list existing VMs with the OP message.

Yes. I removed too the file libvirt.pyc because the upgrade "pacman -Syu" will be sucessfull.

What solution for this bug?? I like kvm and arch very much...

Thanks.

It seems to me that virt-manager 0.10 just doesn't support libvirt and libvirt-python 1.2.

I installed virt-manager-git from aur and that seems to fix that "Exception in thread Tick thread" error but has other problems and isn't usable.

How can I downgrade versions of some packages to fix this problem?

Hi, Same problem here, however i have test with the original sources and the problem still present but isn't clear if the problem goes with virt-manager or some library

@Ivan (Zipfer)
You can use "sudo pacman -U /var/cache/pacman/pkg/libvirt-1.1.4-1-x86_64.pkg.tar.xz" or another version. If this will fail, try to remove "libvirt-python" package.

I'm spanish;

I can confirm, that Zipfer's suggested method works for me:

sudo pacman -R virt-manager
sudo pacman -R libvirt-python
sudo pacman -R libvirt-glib
sudo pacman -R libvirt
sudo pacman -U libvirt-1.1.4-1-x86_64.pkg.tar.xz
sudo pacman -U virt-manager-0.10.0-3-any.pkg.tar.xz

virt-manager now works.

Where should I download these package? my pacman cache is empty...

Yeah, this solved the problem getitem, but I have other error:

You can find old version of packages as described here - https://wiki.archlinux.org/index.php/Arch_Rollback_Machine

This is caused by a broken libvirt-python build. See https://bugs.archlinux.org/task/38027

It works for me again. Wow! I guess libvirt-python 1.2.0-2 resolved the issue. It only works with virt-manager, not with virt-manager-git. (The problem persists with the latter.)

I can confirm everything's back to normal with livbirt-python 1.2.0-2.

Confirm as fixed here too after updating libvirt-python to 1.2.0-2.
