I am seeing that message, too, on a RHEL 4 box. It is happening at boot, in my case, as soon as the login screen is displayed.

This means non-NX/XD support is not complete yet. Can you figure out who
in xenlinux made that request? If you can look at the return address of
the hypercall, you can tell who it is.

If I do an "xm list" after this I am able to see Dom0

When I try to start a VM I get the following error.

SLES9SP2RC3-x86-64:~/xen/vm # xm create vm1
Using config file "vm1".
Error: Error creating domain: 'NoneType' object has no attribute
'getRemotePort'
I did a clean rebuild but this continues to happen. Any idea why
this is happening?
Did you check the error message on the console?
