I found a commit (patch) describing itself only this way: xenstore/tools-xenstore-compatibility.diff Yes, that was the whole of the description. The patch - defines XS_OPEN_DOMAINONLY to 1UL<<2 - arranges that when this flag is passed, xs_open will never try the socket, only the xenstore kernel device - always passes that flag in the xenstore utilities. Digging into snapshot.d.o I found this changelog entry in 4.1.0-2, * Workaround incompatibility with x...
