Re: [Bug 1180777] Re: RDP traffic freeze on quiet network
Hi, I've double checked my conf, I can confirm I'm not using virtio but standard Win 7 drivers. (please see my VM conf that I posted some time ago). So it's not definitely a virtio-specific issue.

Re: [Bug 1180777] Re: Windows 7 VM freeze on Ubuntu 12.04 KVM
Hi, Eventually I've been able to reproduce the hang. Just to recap the experiment: I have recorded network traffic during RDP connection hangs. The result is that the VM has do not experience total network loss: network traffic continues to flow (tcpdump from the host on ports other than 3389).

Hi Serge, I performed the experiment you suggested: 1) Connected with RDP client 2) Worked until it hanged 3) Successfully connected to the VM via virt-manager (RDP client still freezed) 4) Verified that Windows is still connected to the network 5) Successfully pinged my host IP from within the VM (ping 192.168.122.1) So it doesn't seem to be a network disconnect issue.

Re: [Bug 1180777] Re: Windows 7 VM freeze on Ubuntu 12.04 KVM
Hi Serge, In order to reconnect, I have simply restarted another RDP client without any further step required (no need to use VNC and ping, it was just a test to check network connectivity).

So just to be sure, after this did you check whether the RDP client worked again? If not, were you able to re-connect with a new RDP client? If so, then can you also re-connect with a new RDP client without first connecting via VNC and pinging the host from the guest?

Hi Serge, Please find attached the remmina configuration screenshots. Yes, when the RDP connection hangs I simply close the RDP client and start a new one immediately and it works correctly.

Hi Serge, Thanks for the reply. What I meant is that I started using KVM for my virtualization needs, while I was previously using VirtualBox. Sorry for not being clear on this point. Yes the VM continues to run, however it is pretty annoying and can potentially imply that for me Win 7 on KVM is not usable in practice (think about hangs during customer presentations... ).
