No official statement yet, but I think they will support virtualization. There hasn't been an AMD CPU in ages without AMD-Vi/IOMMU.

But lack of ECC support is a problem if you want to use virtualization for security, as Rowhammer can be used for attacking other VMs and ECC is often the last line of defense against Rowhammer.
