Why is it there? How can this be extended/avoided? What version of libvirt are you running? This is a limit set by the RPC code, and it was increased from 256 to 16384 in commit eb635de1fed3257c5c62b552d1ec981c9545c1d7, which looks like it would be in any libvirt *after* 0.9.12 (so any 0.10.x will have the increase).
