Subject: | [Qemu-devel] qemu 2.7.0 incompatible with host kernel < 3.19 |

If the host is running on something lower then 3.19, some guests fail to start. I noticed this on a Ubuntu 16.04 guest, it fails to find the virtio NIC, and this is printed to dmesg:
virtio_net virtio0: virtio: device uses modern interface but does not have VIRTIO_F_VERSION_1
Looking around, I found https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg00373.html , but this does not appear to fully resolve the issue. Any suggestions here? I'm currently just rolling back the upgrade until we can get the kernel upgraded on the rest of the hosts.
