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
