Description

I would like Virtual Machines to have a "Role", just like Devices. They can be taken from the same set of Device Roles.

Use case:

• Being able to tag each VM that its primary role is "Database", "Web server", "Storage server", "Firewall" etc

[jeremystretch]

Does it make sense to use the same set of roles for VMs as for devices though? You wouldn't assign a VM the role of PDU, NAS, console server, etc.

We could either create a separate set of roles only for VMs, or we could extend the existing role model to include a boolean field indicating whether it's applicable for VMs.

I like the boolean option on the existing model and I think it should also be extended to the platform model as the same argument could be made there.

[darkstar]

At least a NAS could very well be a VM (some hyperconverged solutions use VMs to serve CIFS/NFS to the outside world, and there are clustered and virtualized storage systems that provide multi-tenant capable isolated virtual NAS/SAN instances)

Implemented the base relationship in 6243fbf. Will experiment with adding per-model flags to the DeviceRole model shortly.
