I am trying to do a guest install of FC5 on a FC5 machine. Xen is running. I
am having problems
with setting up a proper guest location for the install.

I did a loop back mount of a DVD iso image for FC5, then shared it with NFS
in theory I want to use this to load my guest in xen.

mount -o loop -t iso9660 FC-5-i386-DVD.iso /mnt

then share /mnt on nfs.

What is the name of your virtual machine? guest1
 How much RAM should be allocated (in megabytes)? 256
 What would you like to use as the disk (path)? /home/myhome/guest1
 What is the install location? nfs:

is the path here correct or do I need a sub directory of the ISO image for
location ?

here is the debug:

Starting install...
libvir: Xen Daemon error : POST operation failed: No such domain guest1a
Failed to get devices for domain guest1
Traceback (most recent call last):
  File "/usr/sbin/xenguest-install.py", line 460, in ?
  File "/usr/sbin/xenguest-install.py", line 451, in main
    start_paravirt_install(name, ram, disk, mac, uuid, src, options.extra)
  File "/usr/sbin/xenguest-install.py", line 331, in start_paravirt_install
    dom = conn.createLinux(cfgxml, 0)
  File "/usr/lib/python2.4/site-packages/libvirt.py", line 207, in
    if ret is None:raise libvirtError('virDomainCreateLinux() failed')
libvirt.libvirtError: virDomainCreateLinux() failed

Has anyone seen this problem and know how to work around it.
