Tested the msi-v4.2-part-3 tag in two different Azure/Hyper-V VMs. One
is a Generation 1 VM that has legacy PCI devices and one is a Generation 2
VM with no legacy PCI devices. Tested hot add and remove of Mellanox
CX-3 and CX-4 SR-IOV NIC virtual functions that are directly mapped into the
VM. Also tested local NVMe devices directly mapped into one of the VMs.
No issues encountered. So for Azure/Hyper-V specifically,
