What is the magic mount sauce?

[Paul Clark]

I want to mount my local CDROM to create a new guest using the 
Paravirtualization.  Other parameters are RAM=512mb, disk=5gig, and 
cpu=1.  I have tried the HTTP and NFS protocols.  I was able to access 
the drive and files from another machines so I know I have the network 
configuration correct.  BUT...  when I pass the location to the 
xenguest-install script and the virt-manager I receive an error about 
the URL.

ERROR: Invalid URL location given: [Errno 14] HTTP Error 404: Date: Sun, 
29 Oct 2006 07:35:11 GMT
Server: Apache/2.2.2 (Win32) PHP/5.2.0-dev mod_ssl/2.2.2 OpenSSL/0.9.8b

Vary: Accept-Encoding
Content-Length: 232
Content-Type: text/html; charset=iso-8859-1

What I think is weird is when I use the Fedora site it works, 
http://download.fedora.redhat.com/pub/fedora/linux/core/6/x86_64/os/

Any ideas?

Can you post the contents of /root/.virt-manager/virt-manager.log which
may give us more info about what's going wrong.

I can only think its some subtle URL / apache config mismatch - the logs
ought to help us identify the cause.

Ok, so its trying to fetch the Xen kernel & initrd images. On the same
machine as virt-manager is running, are you able to do:

  wget http://mormon.home/distro/i386/os/images/xen/vmlinux

And

  wget http://mormon.home/distro/i386/os/images/xen/initrd

Which are the two URLs virt-manager will be looking for here. Since you 
said going to download.fedora.redhat.com works OK, I think you must have
an apache mis-configuration, or the URL itself has a typo perhaps ?

Regards,
Dan.
