Proxmox uses tightvnc java applet for communicating between client -
server VMs. My only issue with the tightvnc interface is that
mouse-scrolling isn't supported. Proxmox has a web-interface for
managing VMs (e.g. starting/stopping/creating... live migration, storing
file-based isos and assigning them to vms, creating bridges, assigning
multiple ips to a vm)
It's been a year since I last used Ubuntu's KVM virtual-manager and
certain items didn't work in the interface like adding a 2nd NIC address
or adding usb pass-through, so resorted to bash and editing with
libvirt. A year is a long time for software in heavy development, so
very interested if virtual-manager supports some of the other features
mentioned that proxmox does.
