Xen's automated testing of libvirt against newer Xen's has found a build
issue which it has bisected down to "blockcopy: expose new API in
virsh".
An instance of the failure can be found in flight 30154:
http://lists.xen.org/archives/html/xen-devel/2014-09/msg01063.html

click the header of a failing column =>
http://www.chiark.greenend.org.uk/~xensrcts/logs/30154/build-armhf-libvirt/info.html
click the failing step =>
http://www.chiark.greenend.org.uk/~xensrcts/logs/30154/build-armhf-libvirt/5.ts-libvirt-build.log
virsh-domain.c: In function 'cmdBlockCopy':
virsh-domain.c:2003:17: error: comparison is always false due to limited range of data type [-Werror=type-limits]
cc1: all warnings being treated as errors
It seems to be failing similarly on i386 and I suppose most 32-bit
arches.
Cheers,
Ian.
