Just to be a little pedantic, LXC has definitly be inspired by pre-existing Vserver and OpenVZ. But it's a different implementation.
A lot of things that are viewed as innovations from Docker really already did exist in 2006~2007. Maybe a bit cruder but not that much. OpenVZ was very close to that. AUFS is the only real innovation as far as I know.
Anyway, Docker guys were smart enough to ride the cloud wave and hype the thing. I'm pretty sure Parallels missed the boat because they went the opencore way (OpenVZ/Virtuozzo).
