Hi,
I have configured OpenNebula to use shared NFS for image repo and VM_DIR, e.g.
/groups/one-vm-dir and /groups/one-images-dir are exported from a separate NFS
server, both head-node and cluster-nodes have mounted these shares. Following
is OpenNebula config:
{{{
DB=BACKEND=sqlite
DEBUG_LEVEL=3
DEFAULT_DEVICE_PREFIX=hd
DEFAULT_IMAGE_TYPE=OS
HM_MAD=EXECUTABLE=one_hm
HOST_MONITORING_INTERVAL=600
IMAGE_REPOSITORY_PATH=/groups/one-images-dir
IM_MAD=ARGUMENTS=kvm,EXECUTABLE=one_im_ssh,NAME=im_kvm
MAC_PREFIX=02:00
MANAGER_TIMER=15
NETWORK_SIZE=254
PORT=2633
SCRIPTS_REMOTE_DIR=/var/tmp/one
TM_MAD=ARGUMENTS=tm_nfs/tm_nfs.conf,EXECUTABLE=one_tm,NAME=tm_nfs
VM_DIR=/groups/one-vm-dir
VM_HOOK=ARGUMENTS=$VMID,COMMAND=image.rb,NAME=image,ON=DONE
VM_MAD=ARGUMENTS=kvm,DEFAULT=vmm_ssh/vmm_ssh_kvm.conf,EXECUTABLE=one_vmm_ssh,NAME=vmm_kvm,TYPE=kvm
VM_POLLING_INTERVAL=600
VNC_BASE_PORT=5900
}}}
I am getting following error after creating a VM. The TM is creating disk.0,
deployment.0 and log files in /srv/cloud/one/var ($ONE_LOCATION/var). The VM
dir (/groups/one-vm-dir) contains only deployment.0 file and disk.0 is not
created here. The VMM is failing to create a VM as there is no disk image in
the VM_DIR.

Am I missing something in the configuration here? Any pointers?
Thanks,
