Hi,

instance's resize is something you can do on xenserver only.
I did test it succesfully on XenServer 5.6.
Live migration and block migration are KVM features:
http://wiki.openstack.org/ReleaseNotes/Diablo#Feature_Disparity_KVM_vs_XenServer

To properly setup XenServer you should follow this page:
http://wiki.openstack.org/XenServerDevelopment


Hope it helps
Giuseppe
