Hi,

Sorry I'm replying only now (I've been ill for a couple of days).

So, how's this going? Any more luck? Can I point out to some resources
we have that are related right to what you seem to be after?

http://wiki.xen.org/wiki/Fedora_Host_Installation
http://wiki.xenproject.org/wiki/DomU_Install_with_Virt-Install
http://wiki.xen.org/wiki/Fedora_Test_Days
http://blog.xen.org/index.php/2013/10/16/fedora-virtualization-test-day-report/

In particular, the last two links (Test Days and the blog post) are
something I went through myself last week, so I'm quite sure they're
updated and accurate enough.

In your first e-mail you say you did something like the following:

# virt-install --paravirt --name xen1 --ram 256 --vcpus 1 -f 
/dev/fedora_dhcp1/xen1 --network bridge=br0 --location /mnt/install 
--graphics none

after mounting the install ISO in /mnt/install.

I've actually never done such a thing. If you wanted and HVM guest, I'd
say to try providing virt-install with the ISO directly (something like
'--cdrom <xxx>.iso'. It's probably not on the blog post, but I did it
with a Fedora 20 install DVD image and it worked.

For '--paravirt' I usually point '--location' to an URL from where it
can fetch and perform a network install (and that _is_ in the blog
post :-)), and it pretty much always worked. Can you do that?

There's a '--extra-args' switch which should, if used properly, do
what's needed here, but I'm not use how to set it up properly in this
case (install iso mounted).
