Description of problem Libvirt sometimes complains about getting Invalid string in json text from Qemu Monitor on SPICE_DISCONNECTED event. For the exact message, please see attachment where I attached several examples of such message. it's noticeable when using many VM through RHEVM, after disconnecting spice client from VM. Once one wanna try to connect again, User Portal complains about: "Unexpected exception", vdsm complains about libvirt error, and libvirt complains about wrong json text of SPICE_DISCONNECTED event. Those messages are repeating in logs till the VM is shutdowned. Nothing interesting in qemu output (attaching as well). Version-Release number of selected component (if applicable): qemu-kvm-0.12.1.2-2.177 libvirt-0.9.4-0rc1.2 RHEVM (beta1 - ic136) spice-server-0.8.2-3 Guest: Windows7x32 (with 3.0-14 guest tools), 30GB disk (thin provisioning), latest updates. How reproducible: It's (when you are trying long enough). Steps to Reproduce: 1. Connect to a VM through RHEVM User Portal using spice client. 2. Disconnect from VM (close spice client). 3. Repeat Step 1. and 2. till User Portal prints Unexpected exception and does not open spice session. Actual results: UP: UNexcepted Exception.
