OK, finally got rid of the old aliasing.

I briefly saw the peth0 and vif0.0 interface after doing a "service start xend".

I thought, AHA!  So, I switched off any IPTABLES stuff and rebooted
dom0.

No peth0 or vif0.0.

Also, "service start xend" says nothing and "xend status" says nothing
either.

/var/log/xen/xend.log has this:
[2007-03-16 09:30:48 xend 6160] WARNING (XendAuthSessions:27) python-pam is requ
ired for XenAPI support.

Warning doesn't sound fatal, and a package called "python-pam" does
not exist anywhere on the internet (well, it's referenced as ancient).

Is this the problem?

xend.log also has this from the boot process:
[2007-03-16 09:25:38 xend 5208] WARNING (XendAuthSessions:27) python-pam is 
required for XenAPI support.

This doesn't look good, but who knows what it means?

Nothing should be this hard....it makes Microsoft look good (which is
almost impossible).
