Thanks for the reply.  I think I'm a lot closer than before, but still no cigar.

I've left vncdisplay commented out in the hvm file.  The notes in that
file imply that the default is domid.  However when I try to vnc to
127.0.0.1:33 I get a connection refused.  I then tried to set it to
some random number (tried 5,10,15) and still get a connection refused.
 vnc=1 and vnclisten="127.0.0.1" and vncpasswd='' are set in the hvm
file.

Ah-ha maybe this is part of my problem above.
However I'm having trouble getting virsh to create the domain....

This is on RHEL5,
virsh version
Compiled against library: libvir 0.1.8
Using library: libvir 0.1.8
Using API: Xen 3.0.1
Running hypervisor: Xen 3.0.0

This is what I did:
WinXP is already running as ID=34 (created by xm)
virsh dumpxml 34 >  /etc/xen/winxp2.xml
I then shutdown WinXP.
virsh create /etc/xen/winxp2.xml

libvir: Xen Daemon error : POST operation failed: (xend.err 'Error
creating domain: int argument required')
Failed to create domain WinXP-001
error: Failed to create domain from /etc/xen/winxp2.xml

I looked at xend.log and the following entries all are related to this error:

So what does any of this mean?  Is my virsh broken or something?  How
do I fix this?
Any ideas?

Thanks.
