I mean opensm supports the GUID Alias scheme for virtualization, this
new virtualization scheme is not compatible, and we shouldn't have the
kernel drop support for existing working SMs, by, eg, replacing the
mlx4 guid alias scheme with this new scheme.

[...]

The alias GUID mechanism remains and can be used with mlx4 devices.
With this scheme the admin configures the port and node GUIDs using
iproute2 which ends up in the hardware driver configuring the device.

Indeed. The provisioning through standard means (rtnetlink, iproute2)
would work for both mlx4 (uses Alias GUIDs) and mlx5 (uses
vHCA/vGUIDs).

Or.
