Dear OpenNebula experts,
I am still working on implementing OpenVZ support in OpenNebula
(unfortunately the progress is pretty slow since I am busy with many
other things).
There are the error messages in $ONE_LOCATION/var/<VM_ID>/vm.log and
oned.log similar to the following pattern:
Command execution fail: 'if [ -x "<some command on remote node>" ]; then
<some command on remote node> Creating; else exit 42; fi'
In particular
vm.log:
[...]

"/tmp/one//vmm/ovz/poll" ]; then /tmp/one//vmm/ovz/poll Creating; else

$ONE_LOCATION/var/remotes/vmm/ovz/poll is not yet implemented (at the
moment it is copied from $ONE_LOCATION/var/remotes/vmm/xen/poll) but
$ONE_LOCATION/var/remotes/vmm/ovz/cancel is what already implemented for
OpenVZ and what I am trying to test.
As far as I understand from OpenNebula development docs
$ONE_LOCATION/var/remotes/vmm/xen/poll has to be invoked on remote host
with argument VMID i.e.
'$SOME_PATH_TO_REMOTE_SCRIPTS/vmm/ovz/cancel <VMID>' but as one can see
from vm.log these command is '/tmp/one//vmm/ovz/cancel Creating'
(Creating instead of VMID).
If /tmp/one//vmm/ovz/cancel is invoked on remote machine manually with
VMID as argument i.e.:
$ /tmp/one//vmm/ovz/cancel 26
that script works as expected (stops and deletes VM).
What can be a reason for error messages in vm.log mentioned above? Any
hint how to debug further?
I am using OpenNebula 2.2.0 and my oned.conf is below:
$ grep -v ^# one-2.2.0/etc/oned.conf |uniq
HOST_MONITORING_INTERVAL = 600
VM_POLLING_INTERVAL = 600
VM_DIR=/vz/one/vm
SCRIPTS_REMOTE_DIR=/tmp/one/

VM_MAD = [
name = "vmm_xen",
executable = "one_vmm_ssh",
arguments = "xen",

VM_MAD = [

executable = "one_vmm_ssh",
arguments = "ovz",

HM_MAD = [

VM_HOOK = [

arguments = "$VMID" ]
Thanks in advance,
Nikolay.
