I've recently reinstalled my workstation with Fedora 27, and since doing so, virt-manager has been doing one strange thing.

Every time I open a VM console and then move the mouse into the window, a dialog appears asking me:

Virtual Machine Manager wants to inhibit shortcuts

You can restore shortcuts by pressing Super+Escape.

It doesn't seem to matter whether I click Deny or Allow. In either case, pressing keys such as Ctrl+W are handled by virt-manager, rather than sent to the VM. In that case, for example, instead of deleting a word on the line I'm editing, the window closes.

Before reinstalling my machine, which was also on Fedora 27, I never saw this dialog box.

The only change I can recall making with respect to virt-manager is to add a PolicyKit rule to allow my user to manage system virtual machines without a password:

# cat /etc/polkit-1/rules.d/51-org.libvirt.unix.manage.rules 
polkit.addRule(function(action, subject) {
        if (action.id == "org.libvirt.unix.manage" &&
            subject.user == "error") {
                return polkit.Result.YES;
                polkit.log("action=" + action);
                polkit.log("subject=" + subject);

These are the package versions I have now:

# rpm -q libvirt-daemon virt-manager

The other difference is that now I am on Wayland, whereas before I was using X. When I log in with "Gnome on Xorg", the problem goes away.

How do I prevent this useless dialog from appearing under Wayland, and have command keys such as Ctrl+W be sent to the VM rather than processed by virt-manager?

  • wayland is still under heavy development and there may not be a configuration tweak to solve this problem for you. your best bet for a solution may be to reproduce this with the latest versions, then file a bug with your wayland compositor and/or virt-manager. – quixotic Jan 20 '18 at 22:17
