Package: kvmtool Version: 0.20160203-1 Severity: important I don't think we should ship kvmtool in stretch without a Linux kernel flavour for it. If you agree, please upgrade this bug to serious. Right now the Debian Linux kernel packages don't have CONFIG_NET_9P_VIRTIO and CONFIG_VIRTIO_NET enabled. For kvmtool we probably want a trimmed down Linux flavour for both speed and attack surface reduction.
