[one-users] not difficult questions

Dear OpenNebula Community,

The environment: a VT enabled physical machine with ubuntu 12.04 server OS
and opennebula 3.8.1 front end (KVM, QEMU and libvirtd installed for
hypervisor).

Configure the ~/etc/oned.conf to support HOOKS as below:

VM_HOOK = [
name = "on_failure",
on = "FAILED",
command = "/var/lib/one/var/remotes/hooks/fail.sh",
arguments = "VM $VMID" ]

Create a script /var/lib/one/var/remotes/hooks/fail.sh to capture the
FAILED state event and do desired action.

To create a FAILED state event, after creating a VM image (below 1) is the
VM image creation template) and before creating a VM (below 2) is the VM
creation template), chmod -r /var/lib/image/win-xp-2.qcow2 to remove the
read permission from the VM image file which is referred in the VM image
creation template, but the VM can still be created successfully, while the
VM creation should be failed and there should be error message like "read
permission denied" in the ~/var/oned.log file.

It is much appreciated if anyone can help with this, to explain why the VM
image creation and VM creation process don't work as it should be? Thank
very much !

1) VM image creation template:

NAME = "win-xp-1"
PATH = /var/lib/image/win-xp-2.qcow2
TYPE = OS

2) VM creation template:

HOSTNAME = OneHost
#CONTEXT definition section
CONTEXT=[FILES="/var/lib/one/.ssh/id_rsa.pub
/var/lib/one/image/setcontextvals.bat /var/lib/one/image/sethostname.vbs",
HOSTNAME=WinXP-$VMID,
IP_PUBLIC="$NIC[IP, NETWORK=\"Small network\"]",
PASSWORD=password,
ROOT_PUBKEY=id_rsa.pub,
USERNAME=user]
#CAPACITY Definition
NAME=WindowsXP-NoPers
CPU=1
MEMORY=1024
# OS image, mapped to hda.
DISK=[ DRIVER=qcow2, READONLY=no, IMAGE_ID = 1, TARGET=hda, TYPE=disk ]
FEATURES=[ ACPI=yes ]
# I/O Devices Section
GRAPHICS=[ TYPE=vnc ]
#NETWORK Section:
NIC=[ model=e1000, network = "Small network" ]
#OS and BOOT Options Section
OS=[ ARCH=i686, BOOT=hd ]
#RAW Section
RAW=[ TYPE=kvm ]

Best regards,
Q.D.S.
