I've been using Krdc under KDE3 to connect to Xen virtual machines for a while. I was trying out the krdc from KDE4 because it'd be really useful to me to have tabs available rather than a separate window for each connection. Bookmarks would also be very useful. My machine is Kubuntu Gutsy on x86_32. I actually have an install of KDE4-RC1 on this machine (installed from here http://kubuntu.org/announcements/kde4-rc1.php); however, the KRDC says it comes from KDE4-beta4, which is presumably what shipped with Kubuntu Gutsy at release (?). If that's a problem (e.g. if libraries are mixed up or something) then I can install something else, as long as it's from packages. I'm not clear exactly what apt has done, I just let it do it's thing. When I connect to a Xen virtual machine, I get lots of output saying: krdc(6342)/krdc (VNC backend) VncClientThread::outputHandler: "Got new framebuffer size: 1280x800" many times. krdc swells to gigabytes of memory usage within a couple of minutes. When I disconnect the VNC session, krdc stops growing but doesn't shrink either. The VNC server in use is the built-in one used by Qemu and Xen for serving out virtual machine framebuffers. It's not based on an external VNC server library and it incorporates some slightly non-standard behaviour (e.g. implements an extension to send resize events to the client when the server resolution changes - supported by RealVNC but not many other clients). Please let me know if there's anything you'd like me to try or any more information you need.
