Answering 1 of my own questions:


http://wiki.xensource.com/xenwiki/XenTerminology  for the glossary.


Also has anyone looked into a SCI-like (or SCI) support for sharing memory between HVM’s?

Reading the following left me longing for a glossary or Xen terms and acronyms, is their one?

Additionally, is there a list of “common recipes” for tasks such as sharing memory with HVM guests?  Adding devices to qemu-dm, or modifications to the rombios?
