Your virtualizer needs to support Jumbo frames for any reasonable packet rate. You saying the MTU being at most 1500 means that either your network hardware can't do Jumbo frames (unlikely, in 2020), or that you're not passing through your network properly into the VM.
You'll want to investigate things like virtualized network cards; especially, you do **not** want to do NAT between your VM and your Host.
