Same:
[root at potoroo ~]# time xm create -c recovery
Using config file "/etc/xen/recovery".
Error: Device 5696 (vbd) could not be connected. Hotplug scripts not working.

real    1m44.270s
user    0m0.085s
sys     0m0.046s
[root at potoroo ~]# cat /etc/xen/recovery | grep -Ev '^($|#)'
import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 128
name = "recovery"
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/var/lib/xen/images/recovery.img,hda,w'
       , 'file:/var/lib/xen/images/WindowsXP.img,hdb,w'
       , 'phy:/dev/hda,hdd,r'
       ]

etc
I don't believe /dev/hda has a different meaning from hda, and it seems that 
iomem (which I've not seen documented in this context) specifies "not 
paravirtualised" I/O. I got that from google when trying to solve the problem 
before posting to the list.
