remote-viewer log with --gtk-vnc-debug
Please attach server logs Created attachment 1238795 [details] Log from /var/log/libvirt/qemu/6.9_32.log To get VNC debug it is necessary to re-compile qemu: https://github.com/qemu/qemu/blob/master/ui/vnc.h#L49 vnc specific, reassigning Are there any changes with rebased gtk-vnc ? I'm not seeing anything bad from gtk-vnc logs - all messages show normal operation, until we get this: (remote-viewer:27714): gtk-vnc-DEBUG: vncconnection.c Read error Error receiving data: Connection reset by peer which shows the QEMU closed the VNC client connection. This makes me suspect that QEMU is at fault. To diagnose this, I think you'll need to rebuild qemu with VNC debug turned on and capture a log it produces. It would also be interesting to see of the same behaviour is seen with qemu-kvm-rhev, as that's a newer version of QEMU. Given length of time since 1.5.3 QEMU, there's a fair chance of some VNC/display bug being fixed in QEMU since then. Are you able to obtain the information requested from a debug build of QEMU. If not, there isn't really any way to take this bug forward to resolution. Cannot reproduce with RHEL 7.4 client virt-viewer-5.0-7.el7.x86_64. |
