I want to like XCP-ng. Unfortunately my primary use case is VMs or containers working with attached USB devices. On Xen it seems like an absolute nightmare to passthrough USB or PCI devices other than GPUs (as vGPUs).
Even on Proxmox it has been frustratingly manual.
I’m planning to try out k8s generic device plugins. I don’t really need VMs if containers will cooperate with the host’s USB. I’m sure that will be a bit of a nightmare on its own and I will be right back to Proxmox.
I hope someone will tell me I am wrong and USB can be easy with Xen. I do prefer XCP-ng over Proxmox in many other ways.
