Why not use chroot, or something like LXC?  Both offer isolated 
environments, allowing you to manage multiple system images without risk 
of interference from conflicting packages.

No. They use virtualization because they need to run multiple separate 
operating systems (like Linux and Windows), are doing development and 
can't risk a kernel panic bringing down the whole thing, or can't risk 
one hacked server compromising the whole system.
