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...)?

Hi f3a97, did you tried to connect via VNC when the freeze situation occurs?

Since a couple of weeks ago, we started to reboot the VM diary. With this way, the problem occurs very less.

I added a rtl8139c netcard to the VM and connected through it by RDP - no more freezes. It looks like kvm does not play well with virtio network cards and RDP.

The source for that is at https://github.com/YanVugenfirer/kvm-guest-drivers-windows . Something like commit 9b1b81a731f722efa8df24429649b527a17bf433 might be relevant (assuming the git HEAD has this fixed, which I've not tested). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1180777 Title: RDP traffic freeze on quiet network To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1180777/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
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.
