Hi Navin, I will tentatively schedule a weekly call for every Thursday from 10:00 to 10:30 AM (or up to 11:00 if required). Would this slot work for Veritas? I will confirm the time with the rest of the Red Hat team as well and make changes accordingly. Best, Pavan. On Mon, Jul 30, 2018, 8:56 PM Navin Tah <Navin.Tah@veritas.com> wrote:
Hi Pavan and all:
We have committed the RHV support for next release of NetBackup. It would help if we can have a weekly/bi weekly call for next 2 months. If there are no topics then we can cancel the call.
Please let us know if this is fine and we can send a calendar invite.

Thanks Navin

Hi Pavan Is it possible to discuss this over a call/webex? It will help us put up our perspective and we can discuss options.
Let us know! -Suchitra

Hi Ondra and team
Thanks for helping us out on below answers.
We recently have reported bug using Bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1608452
This is regarding download of snapshot disk, having multiple snapshots before creation of snapshot for backup. We have observed that in case of multiple snapshots, the caller needs to keep track of the chain and have them in the same order while uploading them back.
Is this a correct understanding? We were looking for an alternate approach of downloading entire disk using snapshot ID XXX, which is created for backup purpose, with REST API (i.e. using proxy_url and signed ticket). We could achieve this if this only if it was a first snapshot when the actual size is same as the provisional size and not for interleaved snapshots.
Kindly advise if that's possible.

Hello oVirt Development team____
__ __
We had some more questions as we continue working on REST APIs. Kindly help us answer the same. ____
__ __
What is the expiry of generated access_token? ____
*Description: *We have observed that the output of *“/ovirt-engine/sso/oauth/token” *contains a field *“exp”* which points to the date when the access_token is going to expire. In our case, we have seen this value to be 8 days later. However, the access_token gets expired within an hour. We would like to understand exactly what is the lifetime of this access_token? What we are seeing is something unexpected? Is this value configurable by users?
I know you can increase user session timeout in engine-config property called 'UserSessionTimeOutInterval', by default it's one hour (note you must restart ovirt-engine in order to take effect of the change). How the field 'exp' is related, I don't exactly know. Ravi?

How to retrieve the ‘creation_status’ of the snapshot through REST API? ____
*Description: *We see there is a way to get it as part of query snapshot API viz /ovirt-engine/api/vms/<vm_id>/snapshots/<snapshot_id> where the response contains detailed information of snapshot, along with the field *"snapshot_status": "ok". *Just wanted to check if there is another API explicitly devoted to getting the creation status so that we can poll it periodically to know the status?____
At least in CURL, we see there is some URL to fetch the creation status like this /ovirt-engine/api/<vm_id>/snapshots/<snapshot_id> /creation_status/<WHAT_IS_THIS_ID?>"____
The link to creation_status is provided in the response of create snapshot operation, if you do it asynchronously. But it's not recomended to use it that way. As you've described polling the 'snapshot_status' attribute is the best way of waiting for operation to finish.
__ __
*Q.* How to call a DELETE snapshot API with ‘async’ operation as ‘false’? ____
*Description: *The documentation for DELETE snapshot API mentions that the DELETE operation can be invoked synchronously or asynchronously based on the value of the parameter ‘async’. I wanted to perform DELETE operation synchronously, so tried providing this parameter in the body as “<async>false<async>”, still it was doing the operation asynchronously. Please advise on the correct usage of
it.
Same as above the sync/async is incorrect here. Both operations behave the same, but async will return the 'creation_status' which you can poll to get the result, but every operation is implemented differently so I wouldn't recomend to use it.
If you want to be sure the snapshost is deleted I the best way is the run DELETE /api/vms/123/snapshots/456, and then do polling of /api/vms /123/snapshots/456 until it returns 404. This operation unfortunatelly can't be invoked synchronously.

__ __
Hello oVirt Development team____
____
We had a conversation with Pavan Chavva for supporting RHV. He had suggested to contact you with queries related to oVirt APIs we plan to use.____
We have following queries:____
____
__1.__While downloading a snapshot disk, can we identify allocated extents and download only those using oVirt API? We are able to download the disk using the Image Transfer API mechanism. ____
However, this method downloads the entire disk including the non-allocated extents, which is a performance overhead. If this functionality does not exist at this point will it be available in near future?____
____
__2.__Is there an alternate method to transfer a snapshot to and from RHV storage? Are there other methods such as NFS share where we can download snapshot image to and from RHV storage?____
____
Thanks____
