Hi,

I've created a new thread for this problem.

Attaching/Detaching using a IDE controller is not supported in VMware
ESX.This is documented in the new development documentation, platform
notes for VMware ESX [1]:

----8<--------------------

to accomplish disk hotplugging and nic hotplugging (ignore the first
bullet for the latter)

disks need to be attached through SCSI, so their images should have a
DEV_PREFIX=“sd”
VM template that will permit SCSI disk attaches afterwards needs to
have an explicitly defined SCSI controller:

RAW=[TYPE = "vmware",
     DATA = "<devices><controller type='scsi' index='0'
model='lsilogic'/></devices>"]

to use SCSI disk based VMs, it is usually a good idea to explicitly
declare the PCI bridges. This can be accomplished with the following
added to the VM template:

 FEATURES=[PCIBRIDGE="1"]

to accomplish hot migration (through vMotion)
