[CentOS-devel] Problem with xen packages

I am trying the xen 4.2 packages for centos 6.4 from
http://dev.centos.org/centos/6/xen-c6/. I've found that some files are
misplaced. Saving a domain crashes with this error:

[oneadmin at xen var]$ sudo xl save -c 14 checkpoint
Saving to checkpoint new xl format (info 0x0/0x0/461)
libxl: cannot execute /usr/lib/xen/bin/libxl-save-helper: No such file
or directory
libxl: error: libxl_utils.c:363:libxl_read_exactly: file/stream
truncated reading ipc msg header from domain 14 save/restore helper
stdout pipe
libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: domain
14 save/restore helper [11440] exited with error status 255
Failed to save domain, resuming domain

The package xen-runtime puts files in two different places (lib and lib64):



Making symlinks from lib64 to lib of libxl-save-helper, xc_save and
xc_restore files makes this feature work.

Aside this problem the packages are working fine.
