Basic interface to the store consists of two ring buffers, one for each direction. Requests to update the store or for information about the current contents are placed into one ring. Responses and asynchronous notifications of changes are inserted into the other ring. The first ring is written to by domU guests and read from by dom0; the other ring is written to by dom0 and read from by domU > > In particular, how do the xenstore-* commands work on a dom0 and domU? > And when should unix-domain sockets be used to communicate with xenstored? this mostly a xend stuff.
