Device 768 (vbd) could not be connected. Backend device not found error
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,
