Hi Hector,
My network configuration is different than yours - it is not bridged.
Perhaps this might help to diagnose the issue?
I'm now trying to sniff network traffic generated by the VM and see what
happens during RDP hangs: does it still poll outside servers (i.e. google
drive) or will become disconnected?
I'll report the results, stay tuned.

Windows 7 VM freeze on Ubuntu 12.04 KVM

Hi,
I have recently setup a Windows 7 VM on KVM and started using it
through remote desktop.
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...)?
