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.
Namely do these processors support ECC and what virtualisation capabilities do they have (for KVM with full GPU access).
