Yes, that's the new feature in 2.5 (and I _think_ it's the only 
2.5-specific one Haizea depends on; I haven't tested Haizea on 2.4 in a 
long time).

The ElementTree package is used in four Haizea modules (cli.commands, 
cli.rpc_commands, common.opennebula_xmlrpc, and core.leases). Each of 
these has the following line:

import xml.etree.ElementTree as ET

Could you try replacing this line with the following?

try:
     import xml.etree.ElementTree as ET
except ImportError:
     import elementtree.ElementTree as ET

Since ElementTree is not included in Python 2.4, you would also have in 
install it manually. It's very likely that there will be a 
python-elementtree package you can install. Otherwise, you will have to 
download it and install it from http://effbot.org/zone/element-index.htm

Please let me know if this works, and I'll commit the change to SVN.

Cheers!
