[Fedora-xen] Error "Path closed or removed during hotplug" with xen-4.0.1 on Fedora 14 (x86_64)

[Kaustav]

Hi,

I am running xen-4.0.1 on Fedora 14 (x86_64) with kernel 2.6.38-0.rc4. All xen 
modules are loaded correctly.

# lsmod | grep xen
xen_netback            24607  0 [permanent]
xen_gntdev              9063  0
xen_evtchn              5179  1
xenfs                   9917  1

I have created images of Ubuntu (maverick) & Debian (squeeze) using 
xen-create-image. However, when I try to boot the images using xm, I am getting 
the following error (for both Debian & Ubuntu):

# xm create /etc/xen/debian01.cfg -c
Using config file "/etc/xen/debian01.cfg".
Error: Device 51714 (vbd) could not be connected. Path closed or removed during 
hotplug add: backend/vbd/16/51714 state: 1

SELinux is turned off. The disk section of cfg is as follows:
root        = '/dev/xvda2 ro'
disk        = [
                  'file:/home/xen/domains/debian01/disk.img,xvda2,w',
                  'file:/home/xen/domains/debian01/swap.img,xvda1,w',
              ]

I am stuck at this for weeks, and have almost exhausted google hits.

Any help would be highly appreciated.

Thanks & Regards,
Kaustav
