In my former tests we realized a general instability of the
Redhat/Fedora tools to run anaconda inside a DomU. Results where not
always reproducible and often errors occured that could not easily be
debugged.

This seems to be a Fedora-specific issue (we tested a lot of
distributions, and no install tools on no other distribution was that
unreliable) - no wonder Redhat claims Xen to be a not so mature
technology :)

For exactly debugging it, the redhat/fedora Xen list might be a better
place (or, even better, their support teams - this is what you pay for
when using rhel5) to ask.

As a workaround, I can recommend bootstrapping your Rhel5 domU's with
yum, after mounting the target directory manually - or use something
like xen-tools or FAI - fully automatic installation (both made for
Debian, but both work well on Fedora, and can be nicely combined.
