Commit Message

Cole Robinson Jan. 18, 2019, 11:05 p.m.
Convert the vmware/vmx driver to net model enum, which requires
adding enum values for vlance, vmxnet, vmxnet2, and vmxnet3.

Previously vmx would accept case insensitive network model
names via the domain XML, but now it will require names to
exactly match the enum case. For reading from vmx files this
won't matter as the parser does case-insensitive comparison.
But if a user attempts to define/create a VM via custom XML
with the wrong case, it will be rejected. I don't know if
that's actually a usecase here so maybe it doesn't matter.
