[Bug 633186] Re: kvm virtio block device SEGFAULT
The multipath segfaults are this bug: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/488285 and I've patched to fix those. Attached is the output of virsh-dumpxml.xml for one of my VMs. I'm going to try reproducing this this afternoon and will try removing the boot option. ** Attachment added: virsh-dumpxml.xml https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/633186/+attachment/1592952/+files/virsh-dumpxml.xml -- kvm virtio block device SEGFAULT https://bugs.launchpad.net/bugs/633186 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 633186] Re: kvm virtio block device SEGFAULT
Hi, thanks for reporting this bug and helping to make Ubuntu better. I'm still trying to set up a way to reproduce this, but my first suggestion would be to try removing the '-boot c' from the command using virtio. That combination has been known to cause problems. Please let us know if that way boots. ** Changed in: qemu-kvm (Ubuntu) Status: New = Incomplete -- kvm virtio block device SEGFAULT https://bugs.launchpad.net/bugs/633186 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 633186] Re: kvm virtio block device SEGFAULT
Regarding the original segfaults of KVM, it looks like you are having some troubles with multipath (I see segfaults of multipathd as well as IO errors at least right before one of the kvm segfaults). I don't know if that is a hardware fault with the controller, or a bug in the driver that a newer kernel (i.e. from https://launchpad.net/~kernel-ppa/+archive/pre-proposed) might help. In the meantime, could you post the result of 'virsh dumpxml VMNAME for some VMNAME of a working VM? -- kvm virtio block device SEGFAULT https://bugs.launchpad.net/bugs/633186 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
