Actually, the issue for both Linux and Windows guests is resolved by this fix https://gitlab.freedesktop.org/spice/spice-gtk/-/issues/82
You do not need to do anything else just install the latest 0.38 spice- client libs on the host (on Ubuntu 20.04): libspice-client-glib-2.0-8_0.38-2ubuntu1_amd64.deb libspice-client-gtk-3.0-5_0.38-2ubuntu1_amd64.deb spice-client-glib-usb-acl-helper_0.38-2ubuntu1_amd64.deb Then it works properly on all guests I think this ticket can be closed... ** Bug watch added: gitlab.freedesktop.org/spice/spice-gtk/-/issues #82 https://gitlab.freedesktop.org/spice/spice-gtk/-/issues/82 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872527 Title: Clipboard doesn't work 100% of the time in Ubuntu 20.04 (in KVM guests) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1872527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
