K2000 should support VirtIO drivers
With the growing popularity of virtualization hypervisors that require VirtIO drives, Quest should start supporting that. Nutanix with AHV is another example of an environment where VirtIO drivers are required. Everything else we have can handle it, K2000 is the only outlier.
At the moment:
K2000 is not working at all on Nutanix AHV
K1000, even if not officially supported, at least seems working fine
