For what is worth, I had several problems with the gitco packages:
- in xen-3.3 .0 , Java starting to consume all the processing power ( 
the same VM with stock xen from Centos 5.2 was fine in this aspect; see 
my thread started at 
http://lists.centos.org/pipermail/centos-virt/2009-February/000836.html )
- with xen-3.4.1 and 3.4.2 from gitco, an XP HVM failed to start, 
despite working perfectly with stock Centos 5.4
