Ever since gtk-vnc-0.4.2 was released, virt-viewer connections to VMs are almost unusable due to very slow drawing of the VNC screen. virt-manager/virt-viewer are completely unusable as a result. The same bug is reported here: https://bugzilla.redhat.com/show_bug.cgi?id=657542. Reproducible: Always Steps to Reproduce: 1. upgrade to gtk-vnc >= 0.4.2 2. connect to a VM using virt-viewer Actual Results: Screen redraws (both text and GUIs) are painfully slow. Using a mouse is basically impossible. Expected Results: Screen redraws are snappy, just like in gtk-vnc-0.4.1. This is not a bug in libvirt/KVM/virt-viewer/virt-manager as connecting to the VMs using a VNC client that does not use gtk-vnc (like tightvnc) shows no video performance issues.
According to https://bugzilla.redhat.com/show_bug.cgi?id=657847, a patch has been commited to master in december which should be available in 0.4.3. Please give a shot at 0.4.3.
I have gtk-vnc-0.4.3 installed now due to an emerge -uDN. I am having the problem (again). I had downgraded to 0.4.1 back when I figured out that 0.4.2 was the issue. Unfortunately, 0.4.1 is now out of the Portage tree, so I can't downgrade (silly me, I didn't package.mask >= 0.4.2, only =0.4.2).
Install 0.4.3 then and report the problem directly to upstream: https://bugzilla.gnome.org/enter_bug.cgi?product=gtk-vnc Thanks
