Thanks for your help. Below are details you are asking for: 1. We use bridge networking. Three network adapters attached to the VM use the same host bridge interface. There're no errors on this network adapter (e1000e). 2. VM was running linux-based os (customized Debian distribution). 3. We used these VMs to test HA cluster so there was Heartbeat/iSCSI/drbd (quite intensive network test). VMs involved into the cluster were set up on different physical hosts. 4. VM had been running for almost 4 days I suppose before the crash.
I looked also in libvirtd.log and found this (maybe it can help): 2013-08-13 09:31:12.654+0000: 3093: info : libvirt version: 0.9.8 2013-08-13 09:31:12.654+0000: 3093: error : qemuMonitorIORead:513 : Unable to read from monitor: Connection reset by peer 2013-08-13 09:50:59.524+0000: 3093: error : qemuMonitorIORead:513 : Unable to read from monitor: Connection reset by peer 2013-08-13 10:31:18.026+0000: 3093: error : qemuMonitorIO:603 : internal error End of file from monitor Regards ** Attachment added: "qemu log" https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1211722/+attachment/3774923/+files/one-455.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1211722 Title: VM crashes on Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1211722/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
