This is caused by Xen exiting the old qemu-dm and starting a new qemu-dm, even for reboots. With kvm the process is kept. (In reply to Philipp Hahn from comment #1) > This is caused by Xen exiting the old qemu-dm and starting a new qemu-dm, > even for reboots. > With kvm the process is kept. And this is unrelated to noVNC, the same happens with krdc as well; the VNC session needs to be restarted for Xen VMs. Reported again at 2014052721004854 It seems that the reconnect via f5 does not always work...the customer reported this. A new search for the machine (in uvmm) will always get the new vnc session. Xen is OoM; with QEMU the connection persists in most cases. There still are VNC dis-connects when QEMU is restarted, for example on snapshot-revert. <https://github.com/novnc/noVNC/pull/747> should help, so +1 for switching from out very old version to a more recent upstream version (Bug #35428) |
