The next thing to try would be to update to gitco Xen 3.4.2 rpms, > but I guess you switched to ESXi already :) 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
