Seeing JC advertise a FreeBSD VPS product reminded me of an itch I've never been able to scratch. I know about jails at the simple end, and I know about VMware at the complicated end, but I've never been able to figure out what technology underlies the VPS offerings. I help out a friend on a Verio VPS that reports itself as FreeBSD 4.7 w/ a kernel config file named VKERN. There's some concept of a virtual root, a command named 'virtual' works a bit like sudo does for credentials, and there's otherwise an odd mix of "it's all my machine" and "it's a shared server". Is/was there some proprietary virtualization technology in the 4.x days? Is it still alive and kicking somewhere? Anyone have any insights into how these VPS products were built? Thanks, g.
