I tried to reproduce this by passing -u -b 2000M to iperf to force some packets to be dropped, but no crashes yet. -- 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/1211722 Title: VM

Hi, I don't seem able to get gdb to tell me where the failures are. If possible, could you install qemu-kvm-dbgsym (see https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages if needed), fire up such a VM, attach to it with gdb (gdb -p $pid) then print the addresses in question:

Thank you. I found that some packets were dropped on interface working as a bridge port. The same story is on the second server. I don't if this may have impact on this crash. You can find this in logs I attached. Regards ** Attachment added: Logs from affected server

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

Thanks for submitting this bug. Nothing seems unusual other than high vnc port and 3 network interfaces. Can you tell me what os was running in the VM, what sort of workloadi t was running, how the three network interfaces were connected on the host, and how long it was up before it crashed?
