[one-users] Questions about OpenNebula system

Dear OpenNebula Community,

Sent you below email yesterday about not able to generate the desired
FAILED state event (i.e. "read permission denied" when chmod -r
/var/lib/image/win-xp-2.qcow2) to activate the action defined in the
VM_HOOK section in ~/etc/oned.conf.

Moreover, the $VMID (2nd argument defined in the VM_HOOK) can't be passed
to the /var/lib/one/var/remotes/hooks/fail.sh file.

For example, simply defined the fail.sh as:

#!/bin/bash
echo "$1" " $2"

When "onevm resubmit 2014", the fail.sh is activated by other FAILED state
event (not the one specified in below email), the output by echo "$1" "$2"
is "VM" only, while it should be "VM 2014".

Why the $VMID can't be passed to fail.sh when it is activated?

Thank you very much for your help and have a great weekend !

Best regards,
Q.D.S.
