Ah, I looked in tools/libxc/*bsd* but didn't think to look in the kernel itself. > See > http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=patch;h=f09eeed01bc884b37e978f6ec6e3e7a86778ef4b OK, so essentially the requirement is that libxc should see the guest's own ERRNO numbers and changing libxc to use xen's numbers would just be wrong. Which is good, because making that change would be a nightmare! Ian. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
