2.6 definitely has virtio 1.0 support, however libvirt does
not yet allow you to control whether a device uses 0.9, 1.0
or both. The default for 2.6 should be both IIRC.

The XML you're looking for is at the end of this message.
Note that a Fedora 24 guest configured this way will not
boot at all if the machine type is virt-2.6; on the other
hand, an identically-configured RHEL 7.3 guest will boot
even with virt-2.6, but both the disk and the network
adapter will be legacy PCI instead of PCIe.
