Open Stack

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.. 

 ps -ef | grep nova

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..

sudo /usr/bin/kvm -S -M pc-1.0 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name instance-00000002 -uuid 3765ec4d-48d0-4f0b-9f7d-2f73ee3a3852 -smbios type=1,manufacturer=OpenStack Foundation,product=OpenStack Nova,version=2014.2,serial=44454c4c-4400-1034-8042-c7c04f313032,uuid=3765ec4d-48d0-4f0b-9f7d-2f73ee3a3852 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/instance-00000002.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc,driftfix=slew -no-kvm-pit-reinjection -no-hpet -no-shutdown -drive file=/opt/stack/data/nova/instances/3765ec4d-48d0-4f0b-9f7d-2f73ee3a3852/disk,if=none,id=drive-virtio-disk0,format=qcow2,cache=none -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/opt/stack/data/nova/instances/3765ec4d-48d0-4f0b-9f7d-2f73ee3a3852/disk.config,if=none,media=cdrom,id=drive-ide0-1-1,readonly=on,format=raw,cache=none

I'm getting below error..

chardev: opening backend "file" failed: No such file or directory

Please help regarding this.

Thanks..
Sonia
