[Bug 331128] Re: virtio on hardy guest and jaunty host (kvm 84) is broken
Okay, with some help from upstream kvm (Anthony Liguori), we have a workaround for this issue in KVM itself. Basically, Hardy's kernel does not support GSO (general segment offload). However, recent kvm/libvirt changes are now utilizing GSO. In the KVM userspace code, we are going to disable this support for all guests until upstream designs a workable mechanism for the host sensing guest support for GSO and use it opportunistically. Uploading to Jaunty now. :-Dustin ** Changed in: libvirt (Ubuntu Jaunty) Status: Confirmed => Invalid ** Changed in: kvm (Ubuntu Jaunty) Status: Incomplete => In Progress ** Changed in: kvm (Ubuntu Jaunty) Assignee: Canonical Server Team (canonical-server) => Dustin Kirkland (kirkland) ** Changed in: kvm Status: New => Confirmed -- virtio on hardy guest and jaunty host (kvm 84) is broken https://bugs.launchpad.net/bugs/331128 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

I've added a task against linux for this bug. I found the following upstream kernel commit (which is in our Jaunty), but not in Hardy.

[Bug 331128] Re: virtio on hardy guest and jaunty host (kvm 84) is broken
Also, try as I might, I have not been able to reproduce this problem using kvm alone on the command line (without libvirt). I see that libvirt was merged twice, from 0.4.6-5ubuntu2 to 0.5.1-4ubuntu1, and then to 0.6.0-1ubuntu1 shortly before Jamie's report. I'm thinking that there may have been a regression somewhere in there. I have posted a message to the kvm upstream mailing list, asking if anyone there is familiar with the problem. Finally, I'm marking this 'Incomplete' against kvm (but leaving it open against libvirt) until someone can show me how to reproduce this problem using KVM alone. :-Dustin ** Changed in: kvm (Ubuntu Jaunty) Status: Triaged => Incomplete ** Changed in: kvm Importance: Unknown => Undecided ** Changed in: kvm Status: Unknown => New ** Changed in: kvm Bugwatch: SourceForge.net Tracker #2067179 => None -- virtio on hardy guest and jaunty host (kvm 84) is broken https://bugs.launchpad.net/bugs/331128 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 331128] Re: virtio on hardy guest and jaunty host (kvm 84) is broken
I believe virtio may be a red herring, this appears to be a problem with any bridge set up using /etc/libvirt/qemu/networks/default.xml By replacing it with default0.xml default1.xml (where %d is replaced with the appropriate number), changing my vm's virsh XML to use those instead of default, then running 'virsh net-undefine default' and then running net-define + net-start for each of the new defaultX.xml's I was able to start some VM's.. the model type emulated appeared to have no effect. Note: Some of my attempted fixes caused CPU sucking infinite loops, and others disassociated libvirt from the running kvm, so backup your disk images before trying to get qemu/kvm/libvirt running in jaunty. -- virtio on hardy guest and jaunty host (kvm 84) is broken https://bugs.launchpad.net/bugs/331128 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

virt-manager is not the culprit because virsh does not work either.
