Yep, did run with --debug (-d) and the XML output has & in it.  I
haven't yet tried the single quote option as a workaround however.

Here is the cmdline generated (per debug output):

  <cmdline>updates=http://yummie.esri.com/updates/updates-el5.1.img ks=http://yummie/ks/ks.php?arch=x86_64&distro=centos&major=5&minor=2 method=http://yummie.esri.com/mrepo/centos5-x86_64/os/</cmdline>

So xend should be able to handle & ?  Or, if my <cmdline> had &
instead of & would xend be able to handle that?

I will try -- but curious if xend is supposed to work in either case.
