the same here. > % dpkg-query -W | egrep > 'linux|kvm|vde|python|libc6|iproute|bridge|adduser|libaio' Basically the same. qemu-kvm 0.12.5+dfsg-1 You aren't using vde, are you? python and adduser are hardly relevant, libaio is only relevant for block i/o and it does not change for quite some time anyway, iproute and bridge utils are not relevant either, because they're used to setup things only, and they do it the same way regardless of version. But it does not hurt to provide that info anyway :) > % virsh start s15 > Domain s15 started > > > (ssh into s15 and generate some traffic, e.g. update-pciids) > > kvm -S -M pc-0.12 -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name s15 -uuid 92dfd544-9638-11df-b6c6-18a905632d8c -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/s15.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -boot cd -drive file=/var/lib/libvirt/iso/grml64,if=none,media=cdrom,id=drive-ide0-0-0,readonly=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive file=/dev/vg_hansolo_dom/vm_s15,if=none,id=drive-virtio-disk0,boot=on,format=raw -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0 -device virtio-net-pci,vlan=0,id=net0,mac=52:54:00:1e:ef:9f,bus=pci.0,addr=0x3 -net tap,fd=64,vlan=0,name=hostnet0 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:15 -k de -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 ugh ;) So the network config is: -device virtio-net-pci,vlan=0,id=net0,mac=52:54:00:1e:ef:9f,bus=pci.0,addr=0x3 -net tap,fd=64,vlan=0,name=hostnet0 Good. > virtio-net truncating packet Oops. So it still exits/aborts with lenny kernel. Oh well. But as far as I can remember, there were indeed some issues with virtio-net in 2.6.26.

Were you able to reproduce this issue with 2.6.33 guest kernel and using qemu-kvm 0.12.4 (the previous one) ? > It seems the problem lies with lenny kernel running inside the VM. Apparently. I'll see if I can find the problem. Please also show `ethtool -k eth0' output on the guest in both cases. If there's something turned on, like e.g. generic segmentation offload (gso), turn that off and retry. I mean the guest that's crashing. Meanwhile, I still can't reproduce the problem locally, for whatever reason it never crashes for me. Trying harder... ;) Thank you for the patience! /mjt -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
