I had a similar problem, and my suggestion is what solved it, but that
was with moonshine, and according to the documentation, the /dev/ shouldn't
need to be specified. I didn't look unto ioemu, as I've never used it and
assumed it had to do with using a different method to emulate (input output
emulation vs block device emulation) since either method would be not
paravirtualised by virtue of the vm being and hvm. However, all of that
(regarding ioemu) is highly presumptious. I seem to recall something about not
being able to have four devices for some reason as well, though, so perhaps you
should do some searching on that premise or try calling it hdc since you aren't
using the cdrom at the same time. I'm not a major linux player or anything, so
I can't make heads or tails of the more detailed output you provided. That
said, my suggestions are shots in the dark. Also, as an aside, I'm assuming -c
works for you on other HVM configs, as the last time I tried it with an
HVM (probably FC6), I don't think it did. Based on the error, though, I don't
think the -c is your problem. If it is, and assuming that you aren't putting
the config file in an auto-start (at boot) location, the hvm config file can
have a setting to start up a vnc window.

Same:
[EMAIL PROTECTED] ~]# 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
[EMAIL PROTECTED] ~]# 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.
