Hey Sonia,
Do the backing file and instance directory exist? "-drive
file=/opt/stack/data/nova/instances/3765ec4d-48d0-4f0b-9f7d-2f73ee3a3852/disk"
implies that both that directory exists and the instance image is contained
within it.

HI
I have install openstack using devstack.I'm using multinode setup with one
controller node and one compute node.I'm able to launch VM from openstack
dashboard onto the controller node.
At the controller node when i do ps -ef | grep nova,the following appears..

I see the VM instance booted using KVM utility on to the controller node.
However when i try to launch VM manually using the similar command but changing
the instances id and name as above..

I'm getting below error..
chardev: opening backend "file" failed: No such file or directory
Please help regarding this.
Thanks..
