Hi list, this morning I've update my centos to 1611. Running virt-manager, and trying to open virt-viewer by clicking on "Open", I get this error: Errore nell'avvio dell'installazione: 'nome-mv' This bug is reported on rh bugzilla (for Fedora 24) and closed 2016-07-02 11:24:51 EDT This problem is locale related. To solve this problem (for other user) I've removed this file: /usr/share/locale/it/LC_MESSAGES/virt-manager.mo. and restarting virt-manager all works fine. Hope that helps for other user with same problem. Best regards. Alessandro.
