[Bug 997978] Re: KVM images lose connectivity with bridged network
Will there be a fix for 10.04 lucid, too? I think this bug affects me too: Windows SBS 2008 with virtio network driver on ubuntu 10.04 lucid host loses network connection from time to time. It's not really deterministic when this error occurs. Usually it happens when there's a large amount of traffic sent over the network. After disabling (via VNC console) the network card in Windows and re-enabling it, everything works fine again, no need to reboot the VM. Any help is appreciated, since it's a quite annoying bug... :-) -- 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/997978 Title: KVM images lose connectivity with bridged network To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/997978/+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

[Bug 404394] Re: qcow2 corruption regression
I found a workaround: Convert your image to RAW and use this in the meantime. This is not the best solution, but at least it prevents from data loss... -- qcow2 corruption regression https://bugs.launchpad.net/bugs/404394 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 315277] [NEW] Ubuntu 8.10 freezes when unattended and recovers after 2 min
Public bug reported: Hello! I recently upgraded from ubuntu 8.04 to 8.10 and now there's one thing that's driving me crazy: As long as I am working, everything is fine. When the screensaver starts and I return to the computer after some minutes and press a key or move the mouse, nothing happens. Another 2 minutes (125.5s, based on 4 measurements) later, the unlock-screen appears and I can continue working. It also happens when watching a movie with VLC, I took the time: after 323s of not moving the mouse oder hitting the keyboard, everything freezed and 91s later, the movie continued. The movie did not continue at the point where it stopped, but 91s later, as if it was still running. I did not press any keys in that time. What is so strange about it: - ping to the freezed computer works, I immediately get replys, so the kernel seems not to be affected - I cannot connect to ssh nor use any existing ssh-session on the server - the hdd-LED is not blinking when freezed, so I assume that all running processes are locked too What I already tried: - running memtest, memory is oaky - changing the screensaver to blank screen - turning of energy save mode for monitor - upgrading to kernel 2.6.27-11 and latest nvidia-mods from intrepid-proposed repository (read that in a forum) Before upgrading to 8.10, I was working with 8.04 and did not experience these problems. I hope we will find out where this bug comes from and find a solution. Please tell me if you need any log-files or more information!
