Hello, 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: --8<------ [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 ------>8-- The package xen-runtime puts files in two different places (lib and lib64): --8<------ /usr/lib64/xen/bin/libxl-save-helper /usr/lib64/xen/bin/lsevtchn /usr/lib64/xen/bin/pygrub /usr/lib64/xen/bin/qemu-dm /usr/lib64/xen/bin/readnotes /usr/lib64/xen/bin/xc_restore /usr/lib64/xen/bin/xc_save /usr/lib64/xen/bin/xenconsole /usr/lib64/xen/bin/xenctx /usr/lib64/xen/bin/xenpvnetboot /usr/lib/xen/bin/qemu-dm /usr/lib/xen/bin/qemu-ga /usr/lib/xen/bin/qemu-img /usr/lib/xen/bin/qemu-io /usr/lib/xen/bin/qemu-nbd /usr/lib/xen/bin/qemu-system-i386 /usr/lib/xen/bin/stubdom-dm /usr/lib/xen/bin/stubdompath.sh /usr/lib/xen/bin/tapdisk /usr/lib/xen/bin/xenpaging ------>8-- 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. Cheers -- Join us at OpenNebulaConf2013 in Berlin from the 24th to the 26th of September 2013!
