How to model the link between the VM guest interfaces and their host counterpart ?

[rgrunbla]

Hello,

I'm using netbox to model my infrastructure which is using proxmox (and other things, of course). VMs on proxmox have interfaces which correspond to tap interfaces on the host, e.g. eth0 (in the VM) and tap100i0 (on the host). I'd like to model this in Netbox, for example with a virtual cable, but it seems I cannot create connections with virtual interfaces, e.g. the documentation states that « only physical interfaces may be connected via cables ». As I do not have the option (it seems) to mark the VM interfaces as physical, what are my option to say that interface X on the host corresponds to interface Y in the VM ?

Thanks !

Is there a compelling reason to match the interfaces of the VMs with their counterpart on the physical host? I don't think it is stable iow it will map to different names over reboots.

For proxmox, it actually is, because the tap interfaces follow the tap<vmid>i<netnum> convention and the VM ID or Net Number do not change.

Can you just create a single object custom field on /virtualization/vm_interface pointing to /dcim/interface to document this relationship? — Mark Tinberg ***@***.***> Division of Information Technology-Network Services University of Wisconsin-Madison
