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).

What happens is that, after some hours of usage, the remote desktop connection freezes. I thought it was a remmina bug, as the it was enough to kill and restart it to successfully connect again to the VM. However, today I've switched to a different RDP client (2X Client chromium app) and the freeze just happened again! Some information: - the host and the VM are completely idle when the freeze occurs - I've tried sniffing the network packets toward the RDP port during the freeze and found that the client is sending packets but no packet is sent back Could this be a KVM issue? How can I further debug this one (I expect the freeze to happen again...)?
