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:

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.
