I have multiple VMs on a host machine (#Proxmox, but I don't think that matters for this question).
I want to have several VMs on a virtual -- i.e. software only -- network inside the Proxmox server. Like there's a little pretend switch, connected to pretend NICs on each VM.
WHAT IS THAT CALLED?
I would've thought "VLAN" meant this, but when I look it up, it seems to be a more expansive term, and people talk about "managed switches", etc.
