What it is XSA-108 is also named "Improper MSR range used for x2APIC emulation". You can read more on the official announcement here. In short, if someone has access to a guest (any DomU) running in HVM, it could crash the host or read any part of the memory: meaning any other guests or the hypervisor itself. That's why VPS vendors were very quick to deal with this problem. Note also with recent Bash...

Containers are not new, with Solaris containers and OpenVZ among several containers technologies going back 2005. But Docker has caught on quickly as mentioned by @adrianco. The startup speed is not surprising for containers, the portability is reminiscent of the Java goal to "write once run anywhere". What is truly interesting with Docker is that availability of Docker registries (e.g Docker Hub) to share containers and the potential to change the application deployment workflows. Rightly so, we should soon see IT move...
