jianghua wang 78f6c1d70b tools/Xen: failed to install domU in new XenServer
Current install_os_domU.sh depends on some keywords which are changed in the
next version XenServer which is upgraded to CentOS 7. So with the existing
script to install domU in the new version XenServer, it will always fail.
This patch is to make it to be compatible with all XenServer versions:
1. the output format of "ifconfig" is changed; the fix is to use the ip
   command to retrieve IP address.
2. In XS 6.5 and the previous XS, the "xe-guest-utilities" package file name
   is as "xe-guest-utilities_<version>_<arch>.deb" but now it delivers a
   single file for all Arch's and the file name is
   "xe-guest-utilities_<version>_all.deb". In order to make it to be
   compatible, the fix will try to search the old file name pattern by
   default. If it does't exist, then try to search the new file name pattern.
