User access to VMs

OK, this should be really simple and I thought it would be pretty obvious and intuitive, but I am going cross-eyed trying to get it to work or to find the answer:

I just set up my first PVE server. Runs smoothly, have Mint and Win7 test VMs running. The console access to the VMs works, but is a hassle, and I am ready to start testing direct browser access to individual VMs. What is the simplest, most reliable way to do this?

Thanks!
