Title:
RDP traffic freeze on quiet network
Status in QEMU:
Expired
Status in qemu-kvm package in Ubuntu:
Expired
Status in Debian:
Incomplete
Bug description:
To summarize what I think has been found so far,
1. The main symptom is that RDP connections hang after some time
2. This bug affects qemu 1.0 .. 1.6.5
3. This bug affects at least windows xp and windows 7 guests
4. Keeping another network connection open, such as vnc, prevents the RDP
connection from hanging.
========================================
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...)?
