        We download boot.iso first, and add kickstart file into it
        recreate a new iso file named custom.iso. We can not tell it is
        rhel6u1 or rhel6u2 from the custom.iso, so remove it before
        creating a new one.

          Every time we install a new guest, we create a folder named 
after the
          name of the guest in root of libvirt-test-API. All of the 
related temporary
          files will be generated in this folder. The custom.iso is 
created in this
          folder. Probably user git clone libvirt-test-API testsuits in 
his/her home
          directory. The qemu process couldn't visit the custom.iso as 
the permission
          problem, the code is to copy the custom.iso into /tmp for qemu 
process.

           I don't think it is a good name either, in v2 it is changed 
to 'delete_checking'
           currently,  the TESTCASE_check is the name supported by 
framework to check
           something before starting test, if just "check" is better 
than "TESTCASE_check"
           we can change it.
