*** Bug 525348 has been marked as a duplicate of this bug. *** Can you attach the output of virsh dumpxml <domain-id>? Created attachment 362741 [details]
Output of "virsh dumpxml <domain>"
I submitted the duplicate of this bug, so not the original bug author, but have the exact same problem.
I create and run my virtual machines from the command line using qemu-img and qemu-kvm, so as far as I know, ther is no <domain-id>. Here is the command line I use to start the VM in question: /usr/bin/qemu-kvm -M pc -smp 3 -m 2000 -k en-us -name yosemite -uuid 677e5aed-0eec-ddff-851d-c07a4a0275a2 -vga std -usb -usbdevice mouse -net nic,macaddr=54:52:00:6d:0d:2f,vlan=0,model=virtio -net tap,script=/etc/qemu-br0-ifup -parallel none -no-reboot -pidfile /var/run/libvirt/qemu/yosemite.pid -soundhw es1370 -smb /sata -cdrom /dev/sr0 -boot c -drive file=/opt/kvm/yosemite/yosemite.qcow2,index=0,if=ide,boot=on Let me know what other information I can provide. I'm a beginner with VM's so please provide detailed instructions for anyting more I need to do. Thanks for the report John! I tried to reproduce this using libvirt and couldn't; it works fine if you use libvirt to start the guest It turns out the reason for this that libvirt is failing to enable GSO support on the tap device, but using qemu-kvm directly *does* enable GSO support So, the bug is likely related to GSO - some guest change between 2.6.29 and 2.6.30 broke GSO support; we'll need to figure out that change was and fix it And we'll also need to figure out why libvirt isn't enabling GSO and fix that too Okay, I found the problem - we need this commit on the stable-0.10 branch: http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commitdiff;h=6e57bb9a63 It seems the offending qemu.git change that this fixes got backported to the stable-0.10 branch. Building this for F-11: * Tue Sep 29 2009 Mark McLoughlin <markmc> - 2:0.10.6-6 - Fix broken virtio-net with 2.6.30 guests (#522994) qemu-0.10.6-6.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/qemu-0.10.6-6.fc11 qemu-0.10.6-6.fc11 has been pushed to the Fedora 11 testing repository.
