[Opensim-users] OpenSim and Virtual Machines

[John Sheridan]

If you're looking to run your own hypervisor I'd suggest something 
called Proxmox.  Its open source / linux based and allows you to create 
both openvz and kvm containers via a nifty web interface. Their website 
is https://pve.proxmox.com
