[Xen-users] libvir: Xen Daemon error : POST operation failed: (xend.err "Error creating domain: (22, 'Invalid argument')")

["andrea15@xxxxxx" <andrea15@xxxxxx>]

I have xen 3.0.3 on fedora 5.
i'm creating a guest domain trough the 
script guest-install.py .
when I try to use an install location I had 
an error:
...Starting install...
libvir: Xen 
Daemon error : could not 
connect to Xen Daemon
Failed to create domain 
...
I updated my libvirt 
and libvirt-python
and now I get a different kind of error when I try 
installing guest domain:
.....
 What is the install location? ftp://ftp.
linux.ncsu.edu/pub/fedora/linux/core/5/i386/os/


Starting install...
libvir: Xen Daemon error : POST operation failed: (xend.err "Error 
creating domain: (22, 'Invalid argument')")
Failed to create domain M1

Now I post the xend.log:
