Hi, This is interesting: 2012-12-03 14:38:25 ERROR nova.compute.manager [req-3e393b4e-d0ed-430f-b0cc-53a9167e6666 afef cep4cma] [instance: d3dba21b-3877-4da3-a2ab-8128f8515573] VHD coalesce attempts exceeded (5), giving up.... Setting instance vm_state to ERROR
Is it possible to get the logs from your XenServer host to tell us what was going wrong when this happened? What is the version of your server, and I am assuming the VM disks are on an EXT3 SR?
