I tried to compile libvirtd 0.7.5 for RHEL5 to test it in our lab an ran into 
major troubles when it comes to KVM integration ....  do you see a realistic 
change that such a new Version is compileable on RHEL5 systems?

A question to a possible workaround: is it possible to limit the maximum time 
for a live migration and ... if exceeded ... fall back to "simple" migration?

Andreas
