Hi all,
I can't find any exhaustive doc for new vdsm-client. My problem actually
is a task (export a vm to OVA) blocked.
I'm afraid you won't find any task in VDSM for 'export a VM to OVA'.
Expoting a VM to OVA is comprised of three steps:
1. Creating temporary cloned disks - you'll find a task of copy-image-group
for each disk.
2. Creating the OVA file - that's done by a python script executed by
ansible, there is no task for that in VDSM.
3. Removing the temporary cloned disks - you'll find a task of remove-image
for each disk.
Can you please elaborate on the problem you're having - where do you see
that task and how can you see that it's blocked?
I found that I can interact with
vdsm-client Task getInfo taskID=<uuid>, and replace getInfo by "stop",
BUT
: how can I find this UUID ???
Old "vdsClient -s 0 getAllTasksStatuses" has no equivalent ??
Does someone knows if a complete doc exists dot vdsm-client ?
Thanks
Frank

Hi All,
vdsClient will be removed from master branch today.
It is using XMLRPC protocol which has been deprecated and replaced by
JSON-RPC.
A new client for vdsm was introduced in 4.1: vdsm-client.
This is a simple client that uses JSON-RPC protocol which was introduced
in ovirt 3.5.
The client is not aware of the available methods and parameters, and you
should consult
the schema [1] in order to construct the desired command.
Future version should parse the schema and provide online help.
If you're using vdsClient, we will be happy to assist you in migrating to
the new vdsm client.
*vdsm-client usage:*
vdsm-client [-h] [-a ADDRESS] [-p PORT] [--unsecure] [--timeout TIMEOUT]
[-f FILE] namespace method [name=value [name=value] ...]
Invoking simple methods:
# vdsm-client Host getVMList
['b3f6fa00-b315-4ad4-8108-f73da817b5c5']
For invoking methods with many or complex parameters, you can read
the parameters from a JSON format file:
# vdsm-client Lease info -f lease.json
where lease.json file content is:
{
"lease": {
"sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2",
"lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5"
}
}
It is also possible to read parameters from standard input, creating
complex parameters interactively:
# cat <<EOF | vdsm-client Lease info -f -
{
"lease": {
"sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2",
"lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5"
}
}
EOF
*Constructing a command from vdsm schema:*
Let's take VM.getStats as an example.
This is the entry in the schema:
VM.getStats:
added: '3.1'
description: Get statistics about a running virtual machine.
params:
- description: The UUID of the VM
name: vmID
type: *UUID
return:
description: An array containing a single VmStats record
type:
- *VmStats
namespace: VM
method name: getStats
params: vmID
The vdsm-client command is:
# vdsm-client VM getStats vmID=b3f6fa00-b315-4ad4-8108-f73da817b5c5
*Invoking getVdsCaps command:*
# vdsm-client Host getCapabilities
Please consult vdsm-client help and man page for further details and
options.
