Yes, we would cut-over to use the XenAPI, but last time I looked it was not
fully backed as well as resource constraints at our end is delaying this.
Still the API as separate rpm/installable entity is required.

We allow this, but need whole xen installed... as there does not seem to be a
good factoring for client side.

This has nothing to do with the packaging on fedora right ? The paramiko had
couple of bugs that got fixed in 1.7.3, so people who have 1.7.3, they do not
have to do this. The patch takes care of detecting the version and doing the
right thing, as 1.7.3 becomes wide spread, it wouldnt be necessary.
For improving the doc, in case you missed, we have the ConVirt wiki, where
everyone can participate and improve. This is going to be a big knowledge
repository. check out at http://www.convirt.net/wiki

Couple of observations, the changes to config file needs to be done on managed
server which would be remote, and hence can not be done as a part of the
install. For the local host management, this is not necessary. So out of the
box, local management should work. On the other hand, people have been asking
for scripts to do this, hence the scripts provided. The scripts also back up
the original file.

Thanks for pointing this out... I will definitely follow up and see whats going
on. I get emails on xenman/convirt issues... but not xen-desktop, this might be
the reason why it got missed.
Thanks again for feedback, and anything else that you can do to help the
project or documentation would be greatly appreciated.

p.s. Just as note, this email does not address the actual problem of having a
client side rpm that can be useful for doing remote xen management. So if
anyone has ideas please let them out :)
