Hi All,

I am getting the error  " xend.err 'Device 768 (vbd) could not be 
connected. Backend device not found " when trying to start the hvm 
domain. So far I have tried Solaris 11 (Nevada) builds 105, build 104, 
build 103 for the xVM server. I am seeing the same issue with all these 
Solaris 11 builds. I am ABLE to create and start the hvm domains using 
Solaris 11 build 93.  I have tried to install Windows 2003 and Redhat 
HVM domains.

#virsh start  reware-vm1

libvir: Xen Daemon error : POST operation failed: (xend.err 'Device 768 
(vbd) could not be connected. Backend device not found.')
error: Failed to start domain reware-vm1

Could someone please help me to solve this issue..?

Thanks a lot,

define config.xml
