Are all Vm2.x images second generation ?
SummaryWhich VM images run on X7 hardware is it all 2.x vms ?
On this Documentation page for Windows servers it states
"Windows: Both VM and bare metal instances, but only on X7/second-generation shapes (shapes with "2" in the name, such as VM Standard 2.16 and BM.Standard2.52). For bare metal, secondary VNICs are supported only on the second physical NIC. Remember that the first physical NIC is NIC 0, and the second is NIC 1. Also see Windows: Configuring the OS for SecondaryVNICs.
Its not clear from this if all Shapes with 2 in the name are X7 or only Windows images with 2 in the name.
