I think kernel 3.16.0 is simply too old. According to the changelog it has been enabled in 3.14.7-1 on all architectures: http://metadata.ftp-master.debian.org/changelogs//main/l/linux/stable_change...
Are you referring to the
* [armhf] Enable VIRTIO_BALLOON and VIRTIO_PCI (Closes: #750742)
entry? That's armhf, not arm64. Or was there a different reference that I missed?
I mixed up armhf and arm64 but …
Anyway, in my 8.5 arm64 guest, virtio-pci doesn't seem to be there at all:
$ grep VIRTIO /boot/config-3.16.0-4-arm64 CONFIG_NET_9P_VIRTIO=m CONFIG_VIRTIO_BLK=m CONFIG_SCSI_VIRTIO=m CONFIG_VIRTIO_NET=m CONFIG_VIRTIO_CONSOLE=m CONFIG_HW_RANDOM_VIRTIO=m CONFIG_VIRTIO=m CONFIG_VIRTIO_BALLOON=m CONFIG_VIRTIO_MMIO=m # CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES is not set
… 4.6.0 has it, including the version available in jessie-backports: $ grep VIRTIO_PCI boot/config-4.6.0-0.bpo.1-arm64 CONFIG_VIRTIO_PCI=m CONFIG_VIRTIO_PCI_LEGACY=y Cheers, -- Guido
