Re: [virt-tools-list] VirtViewer and TCP Keepalives



Hmm, OK

On the Windows locking problem, only my colleague has reported this and yes, the VM does have the latest RHEV Tools installed (3.2-12).

On the timeout, this occurs for both Windows (XP,7,8,2008R2,2012) and Linux (RHEL5/6) VMs.  All we need do to replicate the problem is to leave the SPICE session alone for 15 minutes or so.  How should we go about debugging this?

Thanks

Actually, I can't reproduce: I realized a few minutes later that my wifi card is really crappy, and hangs randomly (I couldn't even connect after that error). I have switch device, and left a client in idle for over 2 hours now, and there is no error so far.
