There isn't any easy way to convert. We could track it in libosinfo but the
vmware bits are quite fine grained. I'm not sure what configuration bits
vmware will change depending on the guestosid, we would need to figure that
out first to know what it properly maps to for libosinfo/virt-install defaults.

Yes they work fine.

--os-variant is used to decide what configuration defaults we will set for the
VM. The classic example is using virtio disk/net for OS that support it
(basically all centos 6+ in this case).

If you want to test it, use the --print-xml option to see how the defaults
change with and without --os-variant
